Question

F(x) =10. I missed part of it in the photo

Answer 1

We have to find the value of x that will give us f(x)=10.

To calculate that, we replace the value of f(x) with 10 and clear x:

`\begin{gathered} f(x)=(1)/(2)x+8=10 \\ (1)/(2)x=10-8 \\ (1)/(2)x=2 \\ x=2\cdot2 \\ x=4 \end{gathered}`

The value of x is x=4, so we conclude that f(4)=10.

Answer: Option C: f(4)
