Chapter 1.7, Problem 5AGP

To determine

The value of the expression $f\left(4\right)$ if $f\left(t\right)=2t^3$ .

Answer to Problem 5AGP

The value of the expression $f\left(4\right)$ if $f\left(t\right)=2t^3$ is $128$ .

Explanation of Solution

Given:

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

Calculation:

Substitute $4$ for $t$ in the expression $f\left(t\right)=2t^3$ as follows:

  $\begin{array}{c}f\left(4\right)=2{\left(4\right)}^3\\ =2\left(64\right)\\ =128\end{array}$

Thus, the value of the expression $f\left(4\right)$ if $f\left(t\right)=2t^3$ is $128$ .
