Question

If f(x) = −3x + 1, find f(−2).

Answer 1

\[f(x)=-3x+1\]
\[f(-2)=?\]
Everytime you see the letter x, replace it with a -2.

Answer 2

That's what they want you to do. ANd then you would get your answer.

Answer 3

whats the answer then?

Answer 4

The term f(x) means a function is written in terms of x.

For f(-2), it's the exact same thing except it is written in terms of -2.

So, with that mind, whenever you come across a "x", just substitute it with a -2.

So, f(-2) = -3 (-2) +1
f(-2) = 6 + 1
f(-2) = 7

\[f(x)=7x+1\]
\[f(-2)=?\]

Answer 10

whats the answer for this question ?

Answer 11
