To determine the value of a function at a specific point, such as when x = 2, you need to know the function itself. For instance, if you have a function defined as f(x) = 3x + 1, you can find the value at x = 2 by substituting 2 into the function.
Here’s how you would do it:
- Substitute 2 for x in the function: f(2) = 3(2) + 1
- Calculate the multiplication: f(2) = 6 + 1
- Add the values together: f(2) = 7
Therefore, for the function f(x) = 3x + 1, the value of the function when x = 2 is 7.
Keep in mind, if your function is different, you’ll follow the same process: plug in the value of x into your function and carry out the arithmetic to find the result.
