Question

graphing trig functions. please help

Answer 1

what is it?

Answer 2

i have to put the equation onto a graph and find the amplitude,period,vertical shift,domain and range and the start point

Answer 3

@johnp12

Answer 4

oh um im not to sure

Answer 5

if you didnt know why did you ask lol @johnp12

Answer 6

well can you say what the equation is and we can go from there?

Answer 7

y=a*sin(b(x-c))+d

|a| is amp
c is phase shift
2pi/b is period
d is vertical shift

Answer 8

y=1+4cos theta i have to graph it

Answer 9

cos and sin have the same above information
y=4cos(x)+1

can you identify the amp number?

Answer 10

4

Answer 11

right!
and the phase shift doesn't change from its parent graph since we just have cos(x)
you can say the phase shift is 0 though
since you can write y=4cos(1(x-0))+1

Answer 12

the period is also the same as its parent graph since 2pi/1=2pi

can you identify the vertical shift?

Answer 13

wouldnt it be theta

Answer 14

no remember the vertical shift in y=a*cos(b(x-c))+d is d
so the vertical shift in y=4cos(x)+1 is?

Answer 15

so if there is theta you would put 1 in for it?

Answer 16

if you are saying the vertical shift is 1 you are right
I don't know why we are talking about the variable inside the cosine function.
