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
