Question

What is the period of the function g(x)=2cos(7x+5)+1

Answer 1

Answer:

2π/7

Step-by-step explanation:

A cosine wave is:

y = A cos(2π/T x + B) + C

where A is the amplitude,

T is the period,

B is the horizontal shift,

and C is the vertical shift.

In this case:

7 = 2π/T

T = 2π/7

Answer 2

Answer:

The period the la function  is with the formula that will be explained below

Step-by-step explanation:

The period is calculated with this formula:

                   2 π

                     b

The absolute value is the distance between a number and zero, therefore the distance between zero and 7 is therefore 7; therefore we finally have:

Periodo:  

                                 

2 π

  7
