<PRE><B>Question 1045703</B>
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
: 
{{{ graph( 300, 200, -5, 2, -10, 10, x^2+3x+2, (1/2)*(-3+sqrt(4x+1)), (1/2)*(-3-sqrt(4x+1)), 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
