Chapter 7.6, Problem 46PPE

To determine

To identify: identify the function has the greater value for the given value of x.

Answer to Problem 46PPE

The function $y=3^x$ has greater value for the given value of x

Explanation of Solution

Given information: The given functions are $y=3^x$ and $y=x^3$

We have the given functions are $y=3^x$ and $y=x^3$

In the function, $y=3^x$ for x=5

  $\begin{array}{c}y=3^x\\ =3^5\\ =243\end{array}$

In the function, $y=x^3$ for x=7

  $\begin{array}{c}y=x^3\\ =5^3\\ =125\end{array}$

Here, we can see that the function $y=3^x$ has greater value for the given value of x
