Q 3. - Precalculus Enhanced with Graphing Utilities

Question

Graph the equation by hand by plotting

points. Use a graphing utility to approximate the intercepts and label them on the graph .

label them on the graph. 

$y=x^2-5$

Step-by-Step Solution

Answer

Intercepts for the given equation are

$x$	$y$	$\left(x ,y\right)$
$0$	$-5$	$\left(0,-5\right)$
$1$	$-4$	$\left(1,-4\right)$
$-1$	$-4$	$\left(-1,-4\right)$
$2$	$-1$	$\left(2,-1\right)$

Graph with the label is.

Step 1. Given information.

Consider the given equation $y=x^2-5$.

Step 2. To find the intercepts for given equation put the values .

Putting the values in equation $y=x^2-5$.

If put x = 0 then y =-5

Similarly x =1 then y = -4

                x = -1 then y =-4

                 x =2 then y = -1

Step[ 3. Plot the graph .

 The graph for the given equation $y=x^2-5$ is shown below.
