The given function is:

$f(x) = x + 3$

This is a linear function of the form $f(x) = mx + b$, where:

• $m = 1$ (slope)
• $b = 3$ (y-intercept)

This function represents a straight line with a slope of 1, meaning it increases at a 45-degree angle. The graph of $f(x)$ crosses the y-axis at $(0,3)$.

Would you like me to evaluate this function for specific values of $x$, find its inverse, or explore related concepts?

Related Questions:

1. What is the graph of $f(x) = x + 3$ and how does it look?
2. How do we determine the inverse of $f(x) = x + 3$?
3. What is the domain and range of $f(x)$?
4. How does the function transformation affect $f(x) = x + 3$?
5. How do you find the x-intercept of this function?

Tip: The slope of a function tells you how fast it increases or decreases. In this case, $m = 1$, meaning for every unit increase in $x$, $f(x)$ increases by 1.
