To find the graph of -f(x) given that f(x) = x + 1, we first need to determine what -f(x) looks like.

  1. Start with the original function: [ f(x) = x + 1 ]

  2. Calculate -f(x): [ -f(x) = -(x + 1) = -x - 1 ]

The graph of -f(x) = -x - 1 is a straight line with a slope of -1, which means it will slant downwards from left to right. The line crosses the y-axis at -1.

Now, you'll want to look at the options provided:

  • The graph of -f(x) = -x - 1 will have:
    • A y-intercept of -1 (where it crosses the y-axis).
    • A slope of -1 (meaning it goes downwards to the right).

Without seeing the graph, you will need to identify the option that matches these characteristics. Look for the line that crosses the y-axis at -1 and has a downward slope.

If you can provide some description of each option’s characteristics, I can assist you in determining which option represents -f(x) = -x - 1.
