If f(x) = 2x -5 and g(2) =22 -4x find (f+g)(x)

Step-by-step explanation:

(f+g)(x) =f(x) +g(x) = 2x-5 + 22-4x = -2x+17

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).

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
