a = 8, b =

Step-by-step explanation:

Given the exponential function

f(x) = a

To find a and b use the given coordinate points on the graph

Using (0, 8 ), then

8 = a [ = 1 ] , then

a = 8

f(x) = 8

Using (2, 18 ) , then

18 = 8b² ( divide both sides by 8 )

= b² , that is

b² = ( take the square root of both sides )

b = =

Thus

f(x) = 8

answer: 45

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
