Help! I have looked at so many lessons on writing exponential functions from a graph and nothing has helped.

y =

Step-by-step explanation:

Let the equation of the exponential function is,

y = a(b)ˣ

Since the graph of this function passes through two points and (3, -1)

For the point ,

---------(1)

For second point (3, -1),

-1 = a(b)³ ---------(2)

Divide equation (2) by equation (1),

=

From equation (2)

-1 =

-1 =

a = 8

Therefore, equation of the exponential function will be,

y =

step-by-step explanation:

if you meant, "on the way from (3, 2) to (3, 14):

x does not change; y increases by 12.
