And I was just wondering if you guys could clarify my answer for me and tell me if I'm correct, or I've made an error.

**Question:**

Consider the function y = 4sin [2 ( x+(2pi/3)] - 5

a) What is the amplitude?

b) What is the period?

c) Describe the phase shift.

d) Describe the vertical translation

e) graph the function. Compare the graph to the properties in parts a) to d)

f) Describe the x-intercepts of the function. Explain your answer

**Answers thus far:**

a) 4

b) pi

c) 2pi/3 to the left

d) 5 units down

e) I have no idea how to graph this :|

f) Also, stumped.

Your thoughts and input are greatly appreciated! thanks!
