A Function F Is Given By F(4x-1) = 4x2+5. Evaluate F(15).
A function f is given by f(4x-1) = 4x2+5. Evaluate f(15).
Answer:905 would be the answer if the function were defined as f(x) = 4x^2+5:
Step-by-step explanation:
But the function is defined as f(4x-1) = 4x^2+5. To evaluate f(15), you need to determine the value of x that makes 4x-1 equal to 15.
4x-1 = 15
4x = 16
x = 4
THAT is the value you need to substitute into the expression 4x^2+5 to get the answer.
