Given the function f(x) = 6x2 −13, what is f(-3)? a. -67 b. -4 c. 41 d. 311

C. 41

Step-by-step explanation:

The quadratic function is:

Then, to find you need to substitute the input value into the quadratic function, to obtain the corresponding output value.

Then, when the  output value is:

This matches with the option C.

-4

Step-by-step explanation:

Please write f(x) as 6x^2 - 13; " ^ " indicates exponentiation.

With f(x) = 6x^2 - 13, we substitute -3 for x in both instances:

f(-3)       =(-3)^2 - 13 = 9 - 13  = -4
