urgent need on this problem !

h(x) = 7 * (9/7) ^x

Step-by-step explanation:

h(x) = a b^x

When x=0 h(x) = 7

7 = a * b^0

7 = a *1

7 =a

Rewriting the equation

h(x) = 7 b^x

Let x=1

9 = 7 * b^1

9 = 7 * b

Divide each side by 7

9/7 =7b/7

9/7 =b

h(x) = 7 * (9/7) ^x

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
