x intercept set y=0 y intercept set x = 0 Vortex can be found by using the equation (2b/a) = x where a = 2 b = +8 in this case, to find the y value sub the x value you get from that equation and you have your vortex To graph just make a table of x values to from 3 to +3 and sub them into the function to see what y values you get then graph the points and intercepts
