Question 285601
g(x) = x^2 + 4x - 6


g(-3) = (-3)^2 + 4*(-3) - 6


g(-3) = 9 - 12 - 6 = -9


graph of x^2 + 4x - 6 is shown below:


{{{graph(400,400,-10,10,-10,10,x^2 + 4x - 6,-9)}}}


Trace a vertical line down from x = -3 and you'll see that it points to the intersection of the graph of the equation with the graph of y = -9.
