Question

F(x)=-3x+5 find f(-2).

Answer 1

f(-2) = 11

Explanation:

f(-2) means to use -2 in place of x.

The problem gave the function:

f(x) = -3x + 5

Now use -2 in place of x.

f(-2) = -3(-2) + 5

= 6 + 5

= 11

f(-2) = 11

Answer 2

Answer: -1

Explanation:

replace x with -2

f(-2) = 3(-2)+5

f(-2) = -6+5

f(-2) = -1
