F(x) = 3x + 2x = 3f-1(x) + 2x - 2 = 3f-1(x)(x - 2)/3 = f-1(x)(14 - 2)/3 = f-1(14)12/3 = f-1(14)4 = f-1(14) f(f-1(14)) = f(4)f(4) = 3(4) + 2f(4) = 12 + 2f(4) = 14 A function and its inverse are inverse operations, like addition and subtraction. They undo each other. f(f-1(x) = x

Answer:

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

Step-by-step explanation:

Given the exponential function

f(x) = a $b^{x}$

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

Using (0, 8 ), then

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

a = 8

f(x) = 8 $b^{x}$

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 $(\frac{3}{2}) ^{x}$
