f\left(\frac{1}{2}\right) = 0.500
\]
\[
f(1.5) = 3.500
\]
\[
f(-1) = -4.000

Here are 5 related questions to expand on this:

1. What is \( f(x) \) when \( x = 0 \)?
2. How would the function \( f(x) = 3x - 1 \) change if the slope were altered to 5?
3. Can you find the x-value where \( f(x) = 0 \)?
4. What is the inverse of the function \( f(x) = 3x - 1 \)?
5. How does changing the constant term in \( f(x) = 3x - 1 \) affect the graph?

**Tip:** Linear functions like \( f(x) = 3x - 1 \) have a constant slope, which means they form straight lines when graphed.
