Aferris wheel with a radius of 13 m is rotating at a rate of one revolution every 2 minutes. how fast is a rider rising when the rider is 18 m above ground level?

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

they can either have 0,1, or infinite solutions
