If f(x) = StartFraction x Over 2 EndFraction + 8, what is f(x) when x = 10?
san4es73 [151]

Answer:

13

Step-by-step explanation:

You are given the function

f(x)=\dfrac{x}{2}+8

To find the value of the function f(x) at point x=a, you have to substitute a instead of x into the function expression.

In your case, you have to evaluate f(x) when x=10. Substitute 10 instead of x into the function expression:

f(10)=\dfrac{10}{2}+8=5+8=13
