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
Step-by-step 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
