Question 289111
Simply graph the polynomial {{{x^2-x-1}}} to get: 



{{{ graph( 500, 500, -10, 10, -10, 10, x^2-x-1) }}}



Now just shade the ENTIRE region below the curve. This shaded region is the red region shown below:


{{{ graph( 500, 500, -10, 10, -10, 10, y<=x^2-x-1) }}}



So why did we shade below? Since f(x) is really 'y' and f(x) is less than or equal to {{{x^2-x-1}}}, this means that all of the y values that satisfy {{{y<x^2-x-1}}} will be below the curve.
