Strategic Advice: Understanding the language of functions will make answering this question very simple. Another way of saying For what values of x does f(x) = –4? is What is the x-value when y = –4?

Getting to the Answer: Draw a line across the graph at y = –4 and find the x-coordinates of any points that hit your line.

The line hits the graph at x = –7 and at x = 5.
