Question: 1 / 400

If f(x) = 3x - 1, what is the value of f(2)?

4

5

To find the value of f(2) when f(x) = 3x - 1, you need to substitute the value of x into the function.

By substituting 2 for x in the function:

f(2) = 3(2) - 1

First, calculate 3 multiplied by 2, which gives you 6. Then, subtract 1 from 6:

6 - 1 = 5

Therefore, the value of f(2) is 5. This means the correct answer is indeed 5, confirming that the calculation directly follows from the definition of the function.
