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 =

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

answer: h
