Given a graph without an equation, how would i figure out f(2), f(-2), f-1(0) and f-1(2)?

OpenStudy (amistre64):

y=f(x). So, f(2) means that at x=2, y=? . And f(-2) means that at x=-2, y=? . f-1(x) is the inverse of f(x). f-1(0) means; what value is x when y=0. And f-1(2) means; what is the value of x when y=2.
