Acosine function has a period of 5, a maximum value of 20, and a minimum value of 0. the function is not a reflection of its parent function over the x-axis. which function could be the function described?

Option (c) is correct.

Step-by-step explanation:

We are asked to find a cosine function has a period of 5, a maximum value of 20, and a minimum value of 0. Also the function is not a reflection of it's parent function over the x-axis.

     To make a cosine function such that the period will be 5 we                    have to change the angle x to .

so, either of (a) or (c) option is correct.

           Hence (a) option does not hold true.

so we are left with only option (c)

Also we know that the range of lie between -1 to 1.

Hence the maximum value for function in option (c) will be 20( When ) and minimum value will be 0( when ).

Hence the resultant function is:

Option C. is correct.
