Three equivalent equations for f(x) are shown. Select the form that reveals the value of the x-intercepts without changing the form of the equation.

Question

A. f(x)= -2x² +4x +6

B. f(x)= -2(x-1)² + 8

C. f(x)= -2(x-3)(x+1)

Answer 1

Answer is C. The x intercept is when y = 0 and the last equation allows you to see that y = 0

when x = 3 & -1
