The domain is the first number of any ordered pair--the x-coordinate.
For example, in the ordered pair (3,4), the domain is 3.
Find the x intercepts by setting each x to equal 0:
(4-x)=0
4 -4 = 0
First x intercept = (4,0)
(x+2) = 0
-2 + 2 = 0
Second x intercept = (-2,0)
Now find the Y intercept by setting the x's to 0 and solve for y:
y = (4-0)(0+2)
y = 4*2
y = 8
The Y intercept is (0,8)
Now find the graph the the parabola crosses the x axis at -2 and 4 and also crosses the Y axis at 8.
Graph A is the correct one.

Answer:
Z-score = 1.18
Step-by-step explanation:
The z-score measures how many standard deviations from the mean a data is
Therefore the z score is the quotient between the difference between a value and the mean and the standard deviation
Where
μ is the mean, x is a data of the population and is the standard deviation
In this case
Then the z-score is
