The graph of the function f(x) = -1 + 0.5x is shown on the coordinate plane.

For what value of x does f(x) = 0?

For what value of x does f(x) = 0?

Where f(x) = 0 is the x-intercept. That is where the graph crosses the x-axis. Remember, f(x) is the

y-value, so if y is equal to 0, this is the x-intercept. The graph of f is the graph of the equation y = f(x).

y-value, so if y is equal to 0, this is the x-intercept. The graph of f is the graph of the equation y = f(x).

**The value of x, when f(x) = 0 is 2.***Ask Algebra House*
