Answer:
[tex]\begin{gathered} a)\text{ -14} \\ b)\text{ -14} \\ c)\text{ 0} \end{gathered}[/tex]
Explanation:
From the piecewise function shown, we start by comparing the domain of values
a) f(-1)
This is less than zero, so we use the first equation
f(-1) : 7(-1) - 7 = -7-7 = -14
b) f(0)
This is greater than or equal to zero, we use the second function:
7(0) -14 = -14
c) f(2)
This is greater than 0, so we use the second function
We have it that:
f(2) = 7(2) - 14 = 14-14 = 0
