Answer:
A. $1,110
B. 50 units.
Step-by-step explanation:
A. Substitute 
into the function 
for calculate the time in hours required for the worker to produce 18 units:
Now you need to substitute 
into the function 
to calculate the amount in dollars she will be paid for 74 hours:
She will be paid $1,110.
B. To calculate the number of units that the worker needs to produce to be paid $3,030 , you need to substitute 
into the function and solve for T (to find the number of hours she requires to work to be paid $3,030)
Now, substitute 
into and solve for x, to calculate the number of units she produces in 202 hours:
She would need to produce 50 units to be paid $3,030
Answer:
Bottom left.
Step-by-step explanation:
In order for any of them to be the graph of a function you would need that given a value of x, you get no more than one value of y. Zero is fine, you just picked an x out of the domain.
In layman's terms it means that if you grab a ruler, a piece of paper, a pen, and you scan the graph moving the edge parallel to the y axis (ie, vertically) you are allowed to touch the graph only once. Top right is out. Bottom left is ok, bottom right is not: you have infinite points of contact in there.
Top left would be fine, if it wasn't for x = 1. In there you have two values marked with a solid dot. That makes it not the graph of a function.
Answer:
The correct answer is x= 4/5 because you cannot take the root of a negative number
