Question

I need help with this practice I’m having trouble solving itNeed some help step by step If you can. Use Desmos to graph this

Answer 1

Given the function:

`y=-4\cos \mleft((2)/(3)x+(\pi)/(3)\mright)-3`

The graph is attached below:

• The period of the function, T = π-(-2π)=3π.

Thus, the function has been graphed to show at least one full period, the x and y-axes are also clearly labeled above.
