Question

For $f\left(t\right)=2t^3$ find the value.

$f(-5)$.

Step-by-Step Solution

Answer

The value of $f(-5)$ is width="53" style="max-width: none; vertical-align: -5px;" $(-250)$.

Step 1. From question.

The given expression is $f\left(t\right)=2t^3,$

Step 2. To find.

Find the value of $f(-5)$ if width="68" style="max-width: none; vertical-align: -5px;" $f\left(t\right)=2t^3,$

Step 3. Evaluation.

Putting $t=-5$ in we get,

$\begin{array}{c}f\left(-5\right)=2{\left(-5\right)}^3\\ =2\left(-125\right)\\ =-250\end{array}$

 

Hence, the value of $f(-5)$ if $f\left(t\right)=2t^3,$ is $– 250$.
