Answer:

a = 8, b = \frac{3}{2}

Step-by-step explanation:

Given the exponential function

f(x) = ab^{x}

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

Using (0, 8 ), then

8 = ab^{0} [ b^{0} = 1 ] , then

a = 8

f(x) = 8b^{x}

Using (2, 18 ) , then

18 = 8b² ( divide both sides by 8 )

\frac{18}{8} = b² , that is

b² = \frac{9}{4} ( take the square root of both sides )

b = \sqrt{\frac{9}{4} } = \frac{3}{2}

Thus

f(x) = 8(\frac{3}{2}) ^{x}
