Answer:

> The graph of the function is a parabola.

Step-by-step explanation:

1.) The value of f(-10) = 82

-----> This statement is false. You can prove this statement false by plugging the "x" value (-10) into the equation.

f(x) = x² - 5x + 12

f(-10) = (-10)² - 5(-10) + 12

f(-10) = 100 + 50 + 12

f(-10) = 162

2.) The graph of the function is a parabola.

------> The function is a parabola. The highest power any of the variables are raised to is 2. Functions with this characteristic are parabolas.

3.) The graph of the function opens down.

-------> The graph does not open down. Because the coefficient in front of x² is greater than 0, the function opens up.

4.) The graph contains the point (20,-8).

--------> This statement is false. You can prove this statement false by plugging the "x" value (20) into the equation.

f(x) = x² - 5x + 12

f(20) = (20)² - 5(20) + 12

f(20) = 400 - 100 + 12

f(20) = 312

5.) The graph contains the point (0, 0).

--------> This statement is false. You can prove this statement false by plugging the "x" value (0) into the equation.

f(x) = x² - 5x + 12

f(0) = (0)² - 5(0) + 12

f(0) = 0 - 0 + 12

f(0) = 12
