Troubleshooting

Explanation:

These actions are called troubleshooting.

Troubleshooting is used to diagnose the unexpected error while you are performing some action on the computer. For example

You are running skype, and a one-day mic or sound performing unexpected error. What will you do? You have to perform the troubleshooting for MIC and sound to diagnose the problem.

During troubleshooting, you will wizard through steps of the procedure to diagnose the problem step by step. If the problem will be identified, the solution will be suggested.

You may experience sometimes your Wifi router at home not working. For this to identify the unexpected error you will perform the troubleshooting.

In short, troubleshooting is used to diagnose unexpected error while performing some action on the computer. If troubleshooting does not work, then close all the programs running on your machine, then shut down your computer. Wait a couple of minutes, and then start your computer and see, the problem may have been alleviated.

Sketch f(x) = 5x2 - 20 labelling any intercepts.

Norma-Jean [14]

Answer:

The graph of the function is attached below.

The x-intercepts will be: (2, 0), (-2, 0)

The y-intercept will be: (-20, 0)

Explanation:

Given the function

$f\left(x\right)\:=\:5x^2-\:20$

As we know that the x-intercept(s) can be obtained by setting the value y=0

so

$y=\:5x^2-\:20$

switching sides

$5x^2-20=0$

Add 20 to both sides

$5x^2-20+20=0+20$

$5x^2=20$

Dividing both sides by 5

$\frac{5x^2}{5}=\frac{20}{5}$

$x^2=4$

$\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}$

$x=\sqrt{4},\:x=-\sqrt{4}$

$x=2,\:x=-2$

so the x-intercepts will be: (2, 0), (-2, 0)

we also know that the y-intercept(s) can obtained by setting the value x=0

so

$y=\:5(0)^2-\:20$

$y=0-20$

$y=-20$

so the y-intercept will be: (-20, 0)

From the attached figure, all the intercepts are labeled.
