Question

What is the value of f(-9) to the nearst hundredth

Answer 1

For this problem, we are given the expression for a function, f(x), and we need to determine the value of f(-9) to the nearest hundredth.

The expression is:

`f(x)=2^(8+x)+7`

We need to replace "x" with the value "-9", and simplify the expression.

`\begin{gathered} f(-9)=2^(8-9)+7 \\ f\mleft(-9\mright)=2^(-1)+7 \\ f\mleft(-9\mright)=(1)/(2)+7 \\ f\mleft(-9\mright)=0.5+7=7.5 \end{gathered}`

The value of f(-9) is 7.5
