Answer on e2020 is "Start by graphing the cosine function.  Stretch the graph of y = cos(x) so the amplitude is 2.  Draw vertical asymptotes where the graph crosses the x-axis.  Shift the graph of y = 2cos(x) down 3 units.  Use the maximum and minimum points on the graph of the cosine function as turning points for the secant function. "


Graphs are used to represent equations and functions

The equation of the graph is given as:

y = 2sec(x) - 3

In trigonometry, we have:

sec(x) = 1/cos(x) --- reciprocals

Substitute 1/cos(x) for sec(x) in the equation of the graph.

So, we have:

y = 2 * 1/cos(x) - 3

Evaluate the product

y = 2/cos(x) - 3

The above equation means that:

Plotting the graph of y = 2/cos(x) - 3 is the same as the graph of y = 2sec(x) - 3
