1) Solving for x, the following equation:
We're going to isolate the x variable on the left:
The initial function is:
And we know that one solution is r=-2
Answer:
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
take square root of 118 = 10.86278
so the expression which equals 118
10.86278 (squared ) = 118
look, i really didnt understand what u meant but i tried my best !!!!!!!!
HOPE IT HELPED :)
