Question

If the function f (x) is defined by f (x) x/2 - 6 then which of the following is the value of f (10)?a.) -1b.) 2c.) 14d.) 7

Answer 1

We want to evaluate x = 10 at the following function

`f(x)=(x)/(2)-6`

To evaluate a function at a given number, we just need to substitute the variable by the number and calculate.

`\begin{gathered} f(10)=(10)/(2)-6=5-6=-1 \\ f(10)=-1 \end{gathered}`
