Step-by-step explanation:

Susan has 40 minutes left to make cards. It takes her about 10 minutes to make each card. Since four 10's can go into 40, Susan can make 4 cards in that time period.

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.
