To evaluate the function $f(x) = -2x + 5$ for $x = -3$, follow these steps:

1. Substitute $x = -3$ into the function: $f(-3) = -2(-3) + 5$

2. Multiply $-2$ by $-3$: $-2 \times -3 = 6$

3. Add 5: $f(-3) = 6 + 5 = 11$

So, $f(-3) = 11$.

Here are some related questions:

1. What is the value of $f(0)$ for the function $f(x) = -2x + 5$?
2. What is the slope of the function $f(x) = -2x + 5$?
3. How does the graph of $f(x) = -2x + 5$ look?
4. What is the y-intercept of the function $f(x) = -2x + 5$?
5. How would the function change if the slope were $-3$ instead of $-2$?

Tip: When dealing with linear functions like $f(x) = -2x + 5$, the slope (the coefficient of $x$) determines how steep the line is, and the constant term (5 in this case) is the y-intercept, the point where the line crosses the y-axis.
