Answer:
f(x) = x^2 − 2x − 15 ----> (-3,0), (0,-15), (5,0)
f(x) = -x^2 − 2x + 15 ----> (-2,15), (-1,16), (0,15)
f(x) = -x^2 + 2x − 15----> (0,-15), (1,-14), (2,-15)
Step-by-step explanation:
The solutions to quadratic functions are where the function crosses the x-axis. These are known as roots or zeros or solutions to the function. Each function has been graphed below and shows the points for which it has solutions.
