Question

What is the value of f(3) in the function below?
f(x) = 1/4 x 2x

Answer 1

Answer:

f(3) = $\frac{3}{2}$

Step-by-step explanation:

To evaluate f(3) substitute x = 3 into f(x), that is

f(3) = $\frac{1}{4}$ × 2(3) = $\frac{1}{4}$ × 6 = $\frac{6}{4}$ = $\frac{3}{2}$

Answer 2

Answer:

f(3) = 3/2 or 1 1/2.

Step-by-step explanation:

I am assuming the first x means times then we substute x = 3 in the given expression;

f(x) = 1/4 * 2x

f(3) = 1/4 * 2(3)

= 1/4 * 6

= 6/4

= 3/2. or 1 1/2.
