a. [tex]f(2)[/tex]

b. [tex]f(5)[/tex]

c. [tex]f(-4)[/tex]

Choose the correct set of values:

A. 14, 98, 66

B. 16, 98, 66

C. 14, 98, -66

D. 16, 98, -66

Answer :

Final answer:

To find the value of f(x) for different values of x, substitute the given values into the function 4x^2 - 2 and calculate. Therefore, the correct option is a) 14, 98, 66

Explanation:

To find the value of f(x) for different values of x, you need to substitute the given values into the function. In this case, let's calculate:

a) f(2) = 4(2)^2 - 2 = 16 - 2 = 14

b) f(5) = 4(5)^2 - 2 = 100 - 2 = 98

c) f(-4) = 4(-4)^2 - 2 = 4(16) - 2 = 64 - 2 = 62

Therefore, the correct option is a) 14, 98, 66
