Answer & Step-by-step explanation:
When using piecewise functions, the intervals represents what function will be used when given a certain number. So, let's begin.
For f(-3), we will use the first function because -3 is less than -1.
f(-3) = 7/2 + 2(-3)
f(-3) = 7/2 - 6
f(-3) = -5/2
For f(-1), we will use the first function again because -1 equals -1.
f(-1) = 7/2 + 2(-1)
f(-1) = 7/2 - 2
f(-1) = 3/2
For f(3), we will use the last function because 3 equals 3.
f(3) = 1/4(3)
f(3) = 3/4
