7. Following is a statement of a theorem which can be proven using the quadratic formula. For this theorem, a, b, and c are real numbers. Theorem If f is a quadratic function of the form f .x/ D ax2 C bx C c and ac < 0, then the function f has two x-intercepts. Using only this theorem, what can be concluded about the functions given by the followi (a) g .x/ D 8x2 C 5x 2 (b) h .x/ D 1 3 x 2 C

∠cbe and ∠deb are same-side interior angles.

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
