Question

Please help me find the answereither column 1 or column 2

Answer 1

Given

`y=(3)/(4)\cos[3(x+(\pi)/(6))]-5`

Find

Determine each statement is true or not.

Step-by-step explanation

the function is in the form

`A\cos(Bx-C)+D`

where A = amplitude

Period =2pi/B

Phase shift = C/B

here ,

Amplitude = 3/4

Vertical shift = D units

`Period=(2\pi)/(B)=(2\pi)/(3)`

we have given period = 3

so , it is not true

phase shift = pi/6

Vertical shift down 5 units

Final Answer

Therefore , A , C and D are true . only B statement is not true. so , column 2 is correct
