The function you provided, $f(x) = 2x + 2$, defines a linear equation.

If you are asking to evaluate $f(x)$, it is already defined as:

$f(x) = 2x + 2$

But if you meant to evaluate $f(x)$ for a specific value of $x$, please provide that value.

Additionally, for clarity, you mentioned $g(x) = -3x + 2$. Would you like to do anything with both functions $f(x)$ and $g(x)$, such as composition or comparison?

Let me know if you'd like to expand on this or have any other questions!

Here are some related questions:

1. What is the slope and intercept of $f(x)$?
2. How does $f(x)$ compare to $g(x)$ graphically?
3. How do we find the intersection of $f(x)$ and $g(x)$?
4. How can we compose $f(g(x))$ or $g(f(x))$?
5. What happens if we solve for when $f(x) = g(x)$?

Tip: When comparing functions, their slopes tell us how steep the lines are, while their intercepts tell us where they cross the y-axis.
