Math, microeconomics or criminal justice
Y = 16x^2 - 49 = (4x)^2 - 7^2 = (4x-7)(4x+7)
graph the quadratic, it's an upward sloping parabola with x intercepts + and - 7/4, y intercept -49
16x^2 -49 = 0
x^2 = 49/16
x = + or - sqr(49/16) = + or - 7/4
vertex and minimum point is (0,-49) line of symmetry is x=0
