Question 1045703: I need to check my answer for this question, so can you give me your answer to compare with?
Question:
Let the domain of be {-5,-4,-3,-2,-1,0,1,2}
a) Graph the function , the ordered pairs that make up the inverse of the function, and the line y=x on the same coordinate plane.
b) Is the Inverse of this function a function?
c) How are the graphs of the function and its inverse related to the line y=x?

a) red line is f(x) = x^2 +3x +2, green and blue line is the inverse function (1/2) * (-3 + or - sqrt(4x+1)), purple line is y = x

:
b) no, one value in the domain is mapped to two values in the range
:
c) the function f(x) is reflected about y = x to get the inverse
