Answer 1

Answer:

Maximum is 8 while the minimum is -8.

Step-by-step explanation:

If we consider y=cos(x), the maximum is 1 and the minimum is -1.

This is the parent function of y=8cos(x) which has been vertically stretched by a factor of 8.  So now the maximum of y=8cos(x) is 8 while the minimum of y=8cos(x) is -8.
