# What is the amplitude, period, phase shift and vertical displacement of #y=sinx-1#?

##### 1 Answer

Amplitude

Period

Phase shift

Vertical Displacement

#### Explanation:

Consider this skeletal equation:

From

#a = 1# #b = 1# #c = 0# #d = -1#

The **a** value is basically the **amplitude** , which is

Since

and the **b** value from the equation is

^ (use

Since the **c** value is **no phase shift** (left or right).

Finally, the **d** value is **vertical displacement** is
