f(x)= x^2.    if x>1
a) find f(0)
b) find f(1)
c) find f(2)
d) determine Domain and Range

im not following along, please explain with equations. thank you

This is a piecewise function, meaning that each part of the graph has a unique relationship.
You have to evaluate f(x) at x=0 , x=1 , and at x=2.  So you need to evaluate f(x) at different domains.
at x=0 , use the part with the interval -1≤x≤1
at x=1 , use the part with the interval x=1
at x=2 , use the part with the interval x>1
