# How do you evaluate the function  f(x)=x^3 for f(2)?

Jun 5, 2018

Plug in $x = 2$ into the equation so it is ${2}^{3} = 8$.

#### Explanation:

If

$f \left(x\right) = {x}^{3}$

then

$f \left(2\right) = {2}^{3} \text{ }$ [here $x = 2$]

$8$

#### Explanation:

Plug in $2$ for $x$:

$f \left(2\right) = {2}^{3}$

$f \left(2\right) = 2 \cdot 2 \cdot 2$

$f \left(2\right) = 8$
