simplify the expression by combining like terms from highest to lowest power of the variable -5a^2 -12a-6a-4-a^2-16-18a^2+5a
Nastasia [14]
So to start off, first combine like terms, so all the a^2 with the a^2’s, the a’s with the a’s, and the normal numbers.

Add the -5a^2, the -a^2, and the -18a^2 together.

-24a^2-12a-6a-4-16+5a

Now add the -12a, the -6a, and the 5a together.

-24a^2-13a-4-16

Lastly add the -4 and -16 together.

-24a^2-13a-20

^^That is your answer^^

Hope this helps!

What is the range of ƒ(x) = |x|?<br><br> (–∞, 0)<br> (–∞, ∞)<br> (0, ∞)<br> [0, ∞)
larisa86 [58]

The range of the function f(x) = |x| is [0,∞)

<h3>How to determine the range?</h3>

The function is given as:

f(x) = |x|

The above is the parent equation of an absolute value function.

The above function cannot output any negative value.

This means that:

ƒ(x) >= 0

As an interval notation, we have:

[0,∞)

Hence, the range of the function f(x) = |x| is [0,∞)
