Answer:
A function is defined as an operation on a number, which gives only one output for every input
while graphing a function, the x-ordinate denotes the input and the y-ordinate denotes the output of the function
Now, lets look at the graph
for the input value '4' , we notice that there are 2 possible outputs. The output can be either 2.5 or -2.5
Since there are multiple outputs for almost every input, this graph cannot denote a function since a function gives only one output

Answer:
Mustafa's pretax income is $59,808.
Step-by-step explanation:
Given in the question Mustafa's annual salary = $67,200
and Mustafa contribute 11% of his salary to his 401 k plan.
Since we know that 401 k plan is a retirement plan in which an employee gets the exemption from his salary on a pretax basis.
Therefore exemption will be = 11% of $67,200
= 67,200×0.11
= $7,392
Now pretax income or taxable income = 67,200-7,392 = $59,808
Therefore pretax income of Mustafa is $59,808.
I think it's cost price

Answer:
The student is expected to spend <em>15.4 hours </em>doing homework
Step-by-step explanation:
The scattered plot shows there is a close correlation between the variables. A line of best fit will go through the 'center' of the points. Since we are not required to find an exact line, we'll draw it in red color as shown below
To know the equation of that line, we must take two clear points of it from the graph. We'll pick (28,4) and (4,25)
The equation of a line, given two points (a,b) and (c,d) is

Using the selected points

Simplifying and computing results, the equation is

Using that equation, we can predict how many hours the students will spend doing homework if they spend 15 hours watching TV
=15.4 hours
So the student is expected to spend 15.4 hours doing homework
