Given the function f(x)=8+2x2, calculate the following values:
f(a)=
f(a+h)=
f(a+h)−f(a)/h=

the image of (6, 9) under a dilation is (4, 6). the scale factor is

3x + 4y -25 =0 represents the amount of change sianna should recieve

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
