Question

estimate the zeros of the equation by graphing x^2-12=0

Answer 1

Well, what you have here...is a parabola (x²) and you are subtracting a constant from the entire function...meaning a vertical shift....so you would have a parabola that, instead of starting at the origin (0,0) would start at a point 12 units down....meaning (0,-12) ...from there you can estimate the x-intercepts (zeros)
