Question

For the function y = -1+6 cos (31(x5)), what is the maximum value?

Answer 1

We want to find the maximum value of the function

`y=-1+cos((2\pi)/(7)(x-5))`

The maximum value of this function is the amplitude of the function, that is the highest value of y, graphing the function, we have

From the graph above, we can see that the maximum value is 5.

Hence the answer is 5
