[9.06] Using graphing technology, approximate where the graph of y = 3x2 − 11x − 5 crosses the x-axis.
Oh yeah, I forgot to mention that there are 2 intercepts as it is a Parabola for a Quadractic Equation.
http://www.wolframalpha.com/input/?i=y+%3D+3x2+ −+11x+−+5+ Here is your graph. We want to look at the x values when y=0 (there are two of them).
here is a nice picture with 'graphing technology' http://www.wolframalpha.com/input/?i=y+%3D+3x2+%E2%88%92+11x+%E2%88%92+5+
yw. why you are not just supposed to use the quadratic formula and get exact answers is not clear
