f(x) =
{−8 if −3 ≤ x ≤ 0
{x if 0 < x ≤ 3

Evaluate the given expressions.
a)f(-1)=
b)f(0)=
(^Teach how to do this.)

What is the formula?
a)(−8)*(x > −3)*(x >= 0) + (x)*(x <= 0)*(x > 3)
b)(−8)*(x >= −3)*(x <= 0) + (x)*(x > 0)*(x <= 3)
c) (−8)*(x <= 0) + (x)*(x <= 3)
d)(−8)*(x >= −3) + (x)*(x > 0)

Thank You.
