Since you don't have choices, I can only give you a description of what to look form.
The end behavior of a function is the behavior (direction) of the graph as it approaches positive or negative infinity for the domain. Basically, we are asking where is the graph going on the left side or the right side.
In the given case, as x increases the graph goes down and as x decreases the graph goes up. Look for a similar situation.
Answer:
Mark has 18 shirts
Given that together they have 140 shirts.
x + 7x - 4 = 140
8x = 140 + 4
8x = 144
x = 144/8
x = 18
Joe has 122 shirts
7x - 4
7 × 18 - 4
126 - 4
= 122
It can't be A or D because they have negatives. you can't have negative donuts. you can't have 92.75 donuts therefore it's C
The probability should be 1/60
