Question

If f(x) = -3x^2 +1, then which of the following is the value of f(-2)?

A) -11 B) 37 C) -35 D) -37

Answer 1

Answer:A

Explanation:

Answer 2

To calculate this equation we are gonna follow the PEMDAS order of operation.

F(-2) = - 3x^2 + 1

F(-2) = -3(-2)^2 + 1

Calculate the exponents

(-2)^2 = 4

= -3 * 4 + 1

Now multiply

= -3 * 4 = - 12

= - 12 + 1

Now add

= -12 + 1 = -11

Therefore f(-2) = -11

Then the the solution is option A
