step-by-step explanation:

so just add all then it will be your answer but i am not pretty sur eif it is but hope this i am here to people

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).
