# How do you graph #f(x)=Cos( x + pi/4 ) #?

##### 1 Answer

See explanation.

#### Explanation:

#"Period" = (2pi)/b = (360^@)/b#

#(360^@)/1 = 360^@ "/cycle"#

#"Phase Shift" = -b/c#

#-pi/4 * 1/1 = - 45^@# phase shift

Make a list of points for every

A negative phase shift you'll move the plotted points to the left a positive phase shift adjusts the plotted points to the right.
