Question

If f(x)=2x^2−5(x^2+2) , complete the following statement: f(6)= _____

a) -132
b) -54
c) 54
d) 132

Answer 1

To find f(6), substitute x = 6 into the equation and perform the necessary calculations. The answer is -132.

Step-by-step explanation:

To find the value of f(6), we substitute x = 6 into the equation of the function f(x) = 2x^2 - 5(x^2 + 2).

Relevant steps:

1. Replace x with 6 in the equation.
2. Simplify the equation.
3. Perform the necessary calculations.
4. Write the final answer.

Following these steps, we get f(6) = -132.
