Question

Find points to graph on each quadratic function.
y -1 = 4x^2 + 8x

Answer 1

You can choose any x values to plug in as the domain (the allowable x values of this given quadratic equation are all real values of x, all numbers). Choose x=0 x=1 x=2, x=-1, x=-2 etc and find the y's for each of the x-values. Then you will get coordinate points (x,y)'s.
