Answer:
A) a vertical line does not represent a function.
Step-by-step explanation:
For a relation to be a function for each value of
there must be only one value of
. In other words a function is one in which each value in the domain set corresponds to only one value in the range set.
Let us check for this condition in the give choices:
A) a vertical line
A vertical line is given as
which meas it is parallel to y-axis and has infinite number of
values for a single
value.
So, its Not a function
B) 
For the given equation, on plugging in some
value will give a single
value.
So, its a Function
C) a horizontal line
A horizontal line is given as
which meas it is parallel to x-axis and has infinite number of
values giving a single
value.
So, its a Function
D) {(1, 7), (3,7), (5, 7), (7,7)}
For the given set for different
valuesthere is only one
value.
So, its a Function
Answer:
More information is needed, maximum weekly profit is $1750.
Step-by-step explanation:
The maximum profit would assume Burger King does not sell any burgers on Friday, therefore all 500 burgers were sold at $3.50. 500*$3.50 = $1750 in maximum earnings for the week. More information is needed about the split between the burgers sold over the week.
Maybe the question was trying to say 500 burgers were sold on Friday. In that case, assuming every customer got three burgers, 500/3 = 166.6 customers, rounding down because you cannot have half a customer, 166 customers on Friday. Each customer paid for two burgers 166*2*$3.50 = $1162 in earnings on Friday.
