Question

What is the value of f(-4)

f(x)=-2 if x <-3
4x if -3 \le x \le -1
x^2 if x >-1

Answer 1

to find the value of f(-4),
FIRST, let use find where -4 lands in the domain of this equation. This is a discrete equation. first part is "when x < -3 , then f(x) = -2", in this case we have x = -4. Obviously -4 < -3. condition applied. so we can conclude that f(-4) = -2.
