Question

Use the function below to find f(x)=1/3 4x

Answer 1

The answer to the equation is F(1/3) = 1.33, or, in fraction form, 1 1/3.

Explanation:

What is substitution?

Substitution is the act of replacing a value with a number.

What do we know?

We know the equation is F(x) = 4x.

We also know F(x) = F(1/3).

So, with the information we know, we can solve the problem using substitution.

`F((1)/(3) )=4((1)/(3) )`

`F((1)/(3) )=(4)/(3)`

`F((1)/(3) )=1 (1)/(3)`

Or,

`F((1)/(3) )=1.33`

So, the answer is F(1/3) = 1 1/3 (fraction form) or, 1.33.
