My final answer is (C) because for the side lenghts to be a right triangle, the values of the first and second terms should be equal to the third (a^2 and b^2 =c^2) hope that helped (:
Vlad did not make a mistake.
Answer:
2*2h4g15
Step-by-step explanation:
count how many "g"s there are and same with "h"
Given:
Consider the given function:
To prove:
Solution:
We have,
Substituting 
, we get
Substituting 
, we get
Substituting 
, we get
Using the algebraic formula, we get
![[\because b^2-a^2=(b-a)(b+a)]](https://tex.z-dn.net/?f=%5B%5Cbecause%20b%5E2-a%5E2%3D%28b-a%29%28b%2Ba%29%5D)
[Commutative property of addition]
Now,
Hence proved.
F(-1) = 3
How did I figure this out?
f(-1) is substituted for f(x) so you must look at -1 on the x axis.
Once you've located -1 on the x-axis, locate what it equals to answer the question.
The answer should be the y-axis number that corresponds to -1 which is 3.
