Examine the function defined at right. notice that g(2) = 5. that is when the input x is 2, the output g(2) is 5.
a. when the input is 1. what is the output of the function? that is, find the value of g(1).
b. likewise, what g(- 1) and g(0)?
c. what is the input of this function when the output is -2.5? in other words, find the value of x when g(x) = -2.5. is there more than one possible solution?
