Answer:
f(-1) = -10
f(0) = -6
f(2) = 8
Step-by-step explanation:
As the function says, when x is below 0, the part that we have to use is 7x-3, and when is equal or greater we use 7x-6.
We do so and just replace de values of x in each equation.
[tex]f(-1)=7(-1)-3=-10\\f(0)=7(0)-6=-6\\f(2)=7(2)-6=8\\[/tex]
