Final answer:
The function that has the greatest value for x = 3 is f(x) = 4 • 24
Step-by-step explanation:
Out of the given options, the function that has the greatest value for x = 3 is option B, f(x) = 4 • 24.
To find the value of this function for x = 3, we simply substitute the value into the function: f(3) = 4 • 24 = 96.
Therefore, option B has the greatest value for x = 3.
