HELP ASAP The graph below shows the time it takes Michael to solve 30 multiplication flash cards over 7 attempts. By how many seconds did his time improve from Attempt 1 to Attempt 7? Do not include units in your answer.

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.

the bottom of the spinner is not flat.
