I think the right answer is A
Answer:
The horizontal axis in the coordinate plane is called the x-axis. The vertical axis is called the y-axis. The point at which the two axes intersect is called the origin. The origin is at 0 on the x-axis and 0 on the y-axis.
Answer:
D.
Step-by-step explanation:
Least value = 22 and greatest = 30
Arrange in order:
22 22 23 23 24 25 26 27 28 30
So the median is the mean of the middle 2:
= (24+25)/2 = 24.5.
Also Q1 = 23 and Q3 = 27
So the correct plot is D.
To find invers
1. solve for y
2. replace y with xinverse
so
x=4-4y+y^2
reorder right side
x=y^2-4y+4
factor right side
x=(y-2)^2
squaer root both sides
+/-√x=y-2
add 2 to both sides
2+/-√x=y
switch x and y
2+/-√y=xinverse
xinverse=2+√y or 2-√y
subtract 4 from both sides
2
to work it out just go output f (x) - input x so, 3 - 1 = 2 and double check this using your next equations 4 - 2 = 2
