# Period, Amplitude, Range, Y-intercept and Phase Shift

Develop the solutions for the following problems:

1.) Graph the function y = -1 + 2sin(x + π) over a 2-period interval.

a. What is it's period?

b. What is its amplitude?

c. What is it's range?

d. What is the y-intercept of it's graph?

e. what is it's phase shift?

2.) The formula for the up and down motion of a weight on a spring set in motion is

s(t) = a sin √k/m t

If the spring constant k is 6, what mass m must be used to produce a period of 1 sec.

Hint: period = 2л/w

#### Solution Preview

a function f is periodic with period t if

f(x + t) = f(x)

for all values of x in the domain of f.

Please see the attached figure..

A. From the graph we can see that the funtion has the same value when x = 2pi, 4pi etc. But the least positive value for which such a ...

#### Solution Summary

Period, Amplitude, Range, Y-intercept and Phase Shift are calculated for a given trigonometric function. A formula for weighted spring is elucidated. All work is shown.
