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