Question

If f(x) = −2x + 1, find f(−6).

12

13

−11

−7

Answer 1

Where there is x, put -6

Answer 2

-2(-6)+1
Use order of operations to simplify

Answer 3

Here's an example


This is simple substitution. Where you see an x put in the number 3

f(3) = 2(3) - 1
f(3) = 6 - 1
f(3) = 5 <----------Answer

Answer 4

For this problem that @Ledah has, she (is that right? ) taking f to be
f(x)=2x-1

Answer 5

So for f(x)=2x-1
we can do another example
What is f(-5)
So we are going to replace x with -5
2(-5)-1
Using order of operations
we do multiplication first
-10-1
Now -10-1=-11
So
f(-5)=-11
