a.3
b. pi/2
c. None
d. 2 units upward

amistre64 · Answer

$$y = (amp) trigfunction(\omega(x-(phase.shift)))+vertical.shift$$

amistre64 · Answer

period = ${normal.period\over\omega}$

amistre64 · Answer

the phase shift is pi/2 to the right

anonymous · Answer

4 x pi/ 2 is 2pi amistre..no phase shift at all

amistre64 · Answer

the phase shift is after you factor our the omega; which this appears to be facotred already

amistre64 · Answer

what is the graph shift of: 4(x-1/4)^2?

anonymous · Answer

im just looking at the sine function 
3sin (4x - 2pi) which is 3sin4x

amistre64 · Answer

im looking.....

amistre64 · Answer

i wonder when they changed that ;)

dont try to cram formulae:)
