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 f%28x%29=x%5E2%2B3x%2B2 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?

I'll make you a better deal. You tell us your answer and show your work. If you did it correctly, we'll let you know. If you made an error, we'll show you where you made it and what you need to do to correct it.

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
