Answer:
24
Step-by-step explanation:
If you use Pascal's triangle, which I did, you will look at the 5th row of the triangle which contains the numbers 1, 4, 6, 4, 1
If we expand using a = 2x and b = -1, then the expansion looks like this:
If you simplify all that down by multiplying, you'll get
If you don't know how to use Pascal's triangle, you need to learn. It's so very cool!

i used the pythagorean theorem to find it
Answer:
B the parent function is periodic
Step-by-step explanation:
We can see from the graph that
A it is a polynomial
C that is has 3 real root ( where it crosses the x axis)
D that is contains the point (0,-20)
What is not true is that it is periodic. That would mean it repeats after a certain time.
Find the points and then write them on graph. You basically already have the answer because its all on the graph. First calm down and re-look at it. When your less stressed your less likely to get the answer wrong. Just try. Its all there.
