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.

a. You have to be kidding. is 1 in the region 3 to 0? If so, f(1)=8
Now, which region is x=0 in?
b. second question on formula. All that makes no sense to me. 
I like answer B
