Question

In the xy-coordinate plabe, the graph of the equation y=2x^2-12x-32 has zeros at x=d and x=e, where d>e. The graph has a minimum at (f,-50). What are the values of d, e, and f?

Answer 1

Although we do not know the exact values of the zeros, we can find them by plugging our answers back into the equation. After process of elimination, we come to our answer which is C. Process of elimination is a test taking strategy which often helps in math, especially when quadratic formulas are present.
