To sketch the graph of the function f(x) = -2 + 5, you'll need to plot points on a graph. The equation represents a linear function with a constant value of -2 added to every value of x, followed by an addition of 5 to each resulting value. Here's how you can plot the graph:

1. Choose a set of values for x. Let's say x ranges from -5 to 5 for simplicity.

2. Substitute each x value into the equation and calculate the corresponding f(x) value. For example, when x = -5, f(x) = -2 + 5 = 3. Similarly, when x = 0, f(x) = -2 + 5 = 3, and so on.

3. Create a coordinate plane. Plot the x values on the x-axis and the corresponding f(x) values on the y-axis.

4. Connect the plotted points. Since this is a linear function, you'll notice that the plotted points form a straight line.

In this case, the graph will be a horizontal line passing through the y-axis at the point (0, 3) because the constant 5 does not affect the slope.
