HOW TO: EVALUATE A FUNCTION GIVEN ITS FORMULA

Replace the input variable in the formula with the value provided.

Calculate the result.

Example

Given the function

h(p)=p^{2}+2p

, evaluate

h(4)

.

To evaluate $h(4)$ , we substitute the value 4 for the input variable $p$ in the given function.

{\begin{aligned}h(p)&=p^{2}+2p\\h(4)&=(4)^{2}+2(4)\\&=16+8\\&=24\\\end{aligned}}
