Identify the exponential function whose graph is given below

f(x)= -7 * 2^x

Step-by-step explanation:

The graph of the function goes through the point (0,−7) and (1,−14), so if f(x)= ab^x, then

f(0)= ab^0 = a

f(1)= ab^1 =ab

a=-7 and ab =-14 so,

b= -14/-7 = 2

thus the function is f(x)= -7 * 2^x

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).
