Question

Select the x-intercepts for f(x) = sin (x - Π/2) from 0 to 2Π.

a. 3Π/2
b. Π/2
c. 0
d. 2Π

Explanation would be sweet thanks

Answer 1

you know when y=sin(x) is zero?

Answer 2

This one like the form

f(x) = sin(x - a)

shifts the graph by an amount 'a'

Answer 3

if y = sin(x) intercepts the x-axis for x=0, x=pi, x=2pi
then
y=sin(x - pi/2)
shifts the graph pi/2 units to the right. All the intercepts are pi/2 more now,
x=pi/2, x=3pi/2

Answer 4

thanks!
