Question

What are the period and phase shift for f(x) = 5 tan(2x − π)?

Answer 1

@ganeshie8

Answer 2

is the period pi?

Answer 3

@mathmate

Answer 4

y=Atan(Bx + C) + D
a= amplitude
for tan and cot
period would be \[\rm P=\frac{ \pi}{\left| b \right|}\]
phase shift c/b

Answer 5

p=pi/2?

Answer 6

hmm no for sin and cos period would be 2pi/b
for tan its pi/b

Answer 7

yes that's correct

Answer 8

ok so the period would be pi/2 right

Answer 9

yes

Answer 10

pi/2=phase shift?

Answer 11

hmm C is what ?

Answer 12

What are the period and phase shift for f(x) = 5 tan(2x − π)?

Period: π; phase shift: x = pi over two
Period: π; phase shift: x = negative pi over two
Period: pi over two; phase shift: x = negative pi over two
Period: pi over two; phase shift: x = pi over two

Answer 13

okay so what is C in that equation ?

Answer 14

\[\rm y=Atan(Bx + C) + D\]
f(x) = 5 tan(2x − π)?

Answer 15

-pi/2 as the phase shift?

Answer 16

correct c is negative it's c= - pi

Answer 17

Thanks:)

Answer 18

I have one last question.

Answer 19

Use the graph below to answer the question that follows:

cosine graph with points at 0, negative 1 and pi over 2, 3 and pi, negative 1

What are the amplitude, period, and midline of the function?

Amplitude: 8; period: π; midline: y = 1
Amplitude: 8; period: 2π; midline: y = 5
Amplitude: 4; period: 2π; midline: y = 5
Amplitude: 2; period: π; midline: y = 1

Answer 20

\[\rm y=\color{green}{A}tan(\color{blue}{B}x + \color{Red}{C}) + \color{orange}{ D}\]
\[\rm f(x) = \color{green}{5} \tan(\color{blue}{2}x \color{Red}{− π})+\color{orange}{0} \]

Answer 21

ok. is the answer to the 2d question b?

Answer 22

where is the graph ? and tbh i'm not good at graphing these functions ..

Answer 23

i cant copy it on here:O Just use desmos.com abd type it the points:)

Answer 24

take a scrreenshot like i mean how would i know what is -1 x or y ??
