Graph of 4x + 2y + 3
Definition
The graph of 4x + 2y + 3 is a line in the two-dimensional plane that is defined by the equation 4x + 2y + 3 = 0.What Does It Look Like?
The graph of 4x + 2y + 3 is a straight line with a negative slope. It is parallel to the y-axis, and passes through the origin.Interpretation
The equation 4x + 2y + 3 = 0 can be interpreted as follows: 4x is the amount of x-coordinates present in the graph, 2y is the amount of y-coordinates present in the graph, and 3 is the constant. The equation can be solved for y to find the y-intercept of the graph, which would be y = -3/2.Example
If we were to plot the graph of 4x + 2y + 3, we could plot the points (0, -3/2), (1, -5/2), (2, -7/2), and so on. As we move along the x-axis, the y-coordinates will decrease by -1/2.Conclusion
The graph of 4x + 2y + 3 is a straight line with a negative slope that passes through the origin. It can be interpreted as 4x being the amount of x-coordinates present in the graph, 2y being the amount of y-coordinates present in the graph, and 3 being the constant. The equation can be solved for y to find the y-intercept of the graph.Related Video:

6. What is y- intercept point of the graph below?
Jawaban:
(0,-6)
Penjelasan dengan langkah-langkah:
ingat bahwa y- intercept point (titik potong sumbu y) adalah titik yang memotong sumbu y (vertikal) dan titik bertemunya garis di x=0
lokasinya pada fungsi kuadrat adalah (0,c)
misal...
x² - 2x + 3
a = 1
b = -2
c=3
maka titik potong sumbu y adalah (0, 3)
--------
di grafik, titik potong sumbu y berada di (0,-6)
7. Line l intersects the graph of the function f(x) = 2x² - 4x + 1 at two points where x= -1 and x=2, respectively. What is the slope of line l? a. -2b. -2/3c. 3/2d. 2
when x = -1
y = 2x² - 4x + 1
y = 2(1) - 4(-1) + 1
y = 7
when x = 2
y = 2x² - 4x + 1
y = 2(4) -4(2) +1
y = 1
m (x2-x1) = y2-y1
m (2+1) = 1-7
m = -6/3
m = -2_________

9. mohon bantuannya The picture is a graph of quadratic function......
Persamaan umum fungsi kuadrat :
f(x) = Ax² + Bx + C
Diketahui grafik fungsi f(x) melewati titik :
» (3 , 0)
=> f(3) = 0
=> A.(3)² + B.(3) + C = 0
=> 9A + 3B + C = 0 ( i )
» (–1 , 0)
=> f(–1) = 0
=> A.(–1)² + B.(–1) + C = 0
=> A - B + C = 0 ( ii )
» (0 , 3)
=> f(0) = 3
=> A.(0)² + B.(0) + C = 3
=> C = 3
Subtitusikan nilai C ke ( i ) :
9A + 3B + C = 0
9A + 3B + 3 = 0
9A + 3B = –3 ( iii )
Subtitusikan nilai C ke ( ii ) :
A - B + C = 0
A - B + 3 = 0
A - B = –3 ( iv )
Eliminasi ( iii ) dan ( iv ) :
( iii ) : 9A + 3B = –3
(iv) × 3 : 3A - 3B = –9
________________ +
12A = –12 => A = –1
Subtitusikan nilai A ke ( iv ) :
A - B = –3
–1 - B = –3 => B = 2
Substitusikan nilai A, B, dan C ke persamaan fungsi kuadrat :
f(x) = Ax² + Bx + C
f(x) = (–1)x² + (2)x + (3)
Jadi, persamaan fungsi kuadrat grafik tersebut adalah : f(x)=–x²+2x+3

14. i) the inverse of a function can exists if, and only if, the function f (x) is a one-one mappingii) the domain of f (x) is the domain if f^-1(x)iii) the graph f (x) & f^-1(x) are reflections of each other in the line y=xwhich statement is true?
Subject Function
Statement (i) is wrong. The correct one is that the inverse of the function exists if and only if the function mentioned is bijective function (one-to-one correspondence)
Statement (ii) is wrong. The domain of f(x) is the codomain of [tex] f^{-1}(x) [/tex]
Statement (iii) is wrong.
[tex] f(x) = x \Rightarrow f^{-1}(x)= x [/tex], while y = x and x = y is the same precise equation. The lines are conjoined and hence don't imply what the reflection means.
15. which distance-time graph respresents a body whose speed is decreasing
Which distance-time graph respresents a body whose speed is decreasing is the line on the graph is sloping downwards. Additionally, you may also notice that the distance between points on the graph is getting smaller as well - this, too, is an indication that the speed is slowing down.
PembahasanPada pokok bahasan kinematika, grafik dijadikan salah satu representasi untuk menjelaskan konsep gerak. Konsep-konsep kinematika gerak meliputi perpindahan, kecepatan dan percepatan yang berhubungan dengan fungsi waktu. Bentuk-bentuk gerakan partikel (benda) dapat diketahui dengan menelaah grafik kinematika.
Pada umumnya grafik jarak-waktu ditunjukkan dengan grafik garis yang dapat menjelaskan suatu benda pergerakannya cepat atau lambat dalam waktu tertentu. Ada faktor lain yang dapat mempengaruhi grafik jarak-waktu (seperti percepatan), jadi penting untuk mempertimbangkan semua ini sebelum membuat kesimpulan. Namun, jika Anda melihat kemiringan ke bawah atau jarak antar titik yang lebih kecil, dapat dikatakan bahwa kecepatan yang ditunjukkan oleh grafik memang menurun.
