D

Question 7

Describe how to sketch the graph of y = –tan(2x) + 3 using the parent function.

Revolt · Accepted Answer

To sketch the graph of y = –tan(2x) + 3, start with the parent function y = tan(x). First, compress the graph horizontally so that its period becomes π/2 instead of π. Next, reflect the graph across the x-axis because of the negative sign. Finally, shift the entire graph up 3 units.

Question 8

Where are the asymptotes of the function?

Revolt · Accepted Answer

B: 5pi/2 + 4npi

Question 9

Which of the following did you include in your answer?Start by graphing the tangent function.Compress the graph horizontally by making the period one-half pi.Reflect the graph over the x-axis.Shift the graph up 3 units.

A: Start by graphing the tangent function.; B: Compress the graph horizontally by making the period one-half pi.; C: Reflect the graph over the x-axis.; D: Shift the graph up 3 units.

Question 10

What are the x-intercepts of the function?

Revolt · Accepted Answer

A: 7pi/2 + 4npi
