Answer:
I will assume the equation is supposed to be f(x) = x^2 – 5x + 12 since it is said to be a quadratic equation.
Step-by-step explanation:
See attached graph.
The value of f(–10) = 82   False
   f(-10) = (-10)^2 - 5*(-10) + 12
    f(-10) = (100) +50 + 12
   f(-10) = 162
The graph of the function is a parabola. Â True
The graph of the function opens down. Â False
The graph contains the point (20, –8).    False
The graph contains the point (0, 0). Â Â Â Â Â False
