Chapter 5.6, Problem 90AYU

(A)

To determine

To draw:

The graph of the given function

Explanation of Solution

Given:

The function is

  $\begin{array}{l}f\left(x\right)=5^{x-1}\\ g\left(x\right)=2^{x+1}\end{array}$

Concept used:

Definition of the differentiation:-Differentiation is the action of computing a derivative

The derivative of a function $y=f\left(x\right)$ of a variable $x$ is a measure of the rate at which the value y of the function changes with respect to $x$

Calculation:

The function

  $\begin{array}{l}f\left(x\right)=5^{x-1}\\ g\left(x\right)=2^{x+1}\mathrm{...................}\left(1\right)\end{array}$

Draw the table

  $f\left(x\right)=5^{x-1}$

Test one point in each of the region formed by the graph

If the point satisfies the function then shade the entire region to denote that every point in the region satisfies the function

$x-axis$	$0.43$	$0.68$	$-1$	$-2$
$y-axis$	$1$	$2$	$0.8$	$-0.96$
