5x+21+178/(x-7)<br> How do I solve for domain and range on this equation?
Luda [366]
The domain is easiest. You simply need to find the fractions, and exclude any X that makes the denominator zero. So in this case, your domain is everything except X=7.

For range, you are trying to find out what are the possible answers. Usually the best way to do this is to try x=infinity, and x=negative infinity, which here gives you answers of infinity and negative infinity. Since the function is almost continuous, I think your range is any real number.

Find the numerical values of -3|x|+2x-1 if x=-5. PLSSSS HELP
Kisachek [45]

Answer:

26

Step-by-step explanation:

Since x = -5, we can replace x with it's numerical -5, right? The problem tells you that x is equal to -5. So, just replace any x you see with -5.

So in this case,

-3|x|+2x-1

turns into:

-3|(-5)|+2(-5)-1

You can use a calculator or solve it by hand to see what the answer is.

-3|(-5)|+2(-5)-1\\-3(5)+2(-5)-1\\-15+(-10)-1\\-25-1\\-26
