Answer:
Question 1 Answer : x^2 - 2y^2
Question 2 Answer: x^2
- 36
Answer:
17
Step-by-step explanation:
f(x)= -2x+7
f(-5)= -2(-5)+7
10+7
f(-5)=17
Multiply it out
x^2 + 4x -8x -32
Combine like terms
x^2 -4x - 32
f + 6 = ?
Well, the answer can be pretty much any number. It all depends on what number f is. f is a variable, so you can plug in any number to replace f.
For example, if f was 5, this is what the equation would look like:
5 + 6 = 11
If f was -3, this is what the equation would look like:
-3 + 6 = 3
So, again, the answer can be anything. It depends on what f is.
