Question

given f(x) = 5x-1....what is f(-2) ?

Answer 1

Answer: -11

Step-by-step explanation:

f(-2)=5(-2)-1

f(-2)= -10-1

f(-2)= -11

Answer 2

Answer:

f(-2) = -11

Step-by-step explanation:

x = -2

plug in -2 for x in the given equation:

f(x) = 5x - 1

f(-2) = 5(-2) - 1

Simplify. Remember to follow PEMDAS. First, multiply, then subtract:

5(-2) = 5 * -2 = -10

-10 - 1 = -11

f(-2) = -11.
