![]() ![]() Below you can see a variety of vertical stretches, compressions, and/or reflections on the function f\left(x\right)=x. It is easier to start with a point which is closest to the mirror line (the line of reflection). The segment from F to its image, FF, is perpendicular to the line of reflection y. ![]() This means the larger the absolute value of m, the steeper the slope. EXAMPLE 2 Graph a reflection in y x SOLUTION The slope of y x is 1. There are two kinds of translations that we can do to a graph of a function. Notice in the figure below that multiplying the equation of f\left(x\right)=x by m vertically stretches the graph of f by a factor of m units if m>1 and vertically compresses the graph of f by a factor of m units if 0
