Question

PLEASE CAN SOMEONE HELP ME WITH 2 TRIG QUESTIONS THAT I HAVE BEEN STUCK ON FOR ABOUT 2 DAYS AND NOBODY SEEMS TO HELP ME!

Answer 1

work backwards,
determine your amp, period , phase shift, vertical/ horizontal shift

Answer 2

can someone just show me how to solve the first one so that I can do the second one

Answer 3

hey isn't that from con nexus

Answer 4

what

Answer 5

connections academy

Answer 6

no its from my trig class in Texas

Answer 7

._. hmm bai

Answer 8

can u help me or not?

Answer 9

if that problem is really from where you say it is, can you give me a link so I cam find a solution

Answer 10

@Nnesha you helped me before on these problems, can u help me one last time

Answer 11

oh im not looking to graph, im just trying to find a function out of a graph

Answer 12

@jim_thompson5910

Answer 13

Please help @Vocaloid

Answer 14

#3 has an asymptote, and its range is the set of all real numbers, so the function is either tan or cot

Answer 15

ok

Answer 16

let's assume it's tan(x)

what is the value of tan(x) when x = pi/4

Answer 17

its 1

Answer 18

so IF the point (pi/4, 1) was on the graph, then tan(x) might be the answer. But it's not

Answer 19

something like 4*tan(x) would work

but if we plugged in x = pi/2, then we'd get undefined. The function f(x) = tan(x) is undefined when x = pi/2. So it turns out that tan doesn't even work at all

Answer 20

is this making sense?

Answer 21

i see, so it has to be cotangent

Answer 22

what is the value of cot(x) when x = pi/4 ?

Answer 23

the answer is 1, but if I put a 4 behind cotangent: 4cot(pi/4) then it is 4

Answer 24

good

Answer 25

and it works with the rest as well

Answer 26

so it appears that 4*cot(x) works. Check the other x coordinates to see if it holds up for the other two points

Answer 27

yes 4*cot(x) = 0 when x = pi/2

and 4*cot(x) = -4 when x = 3pi/4

Answer 28

ok so is thar it then, the function for this graphy is just y=4cot(x)

Answer 29

that is it then*

Answer 30

correct

Answer 31

is that how you properly write it down:\[y=4\cot (x)\]

Answer 32

yes

Answer 33

or f(x) = 4*cot(x)

Answer 34

how about the second one, that is the really confusing one

Answer 35

what's the vertical distance from the very peak of one mountain to the very bottom of the valley?
