17x + y = 4
Answers
B) 17x + y = 4 Adding both equations:
5x = 10
x = 2
Since x =2
17x + y = 4
17 * 2 + y = 4
y = 4 -34
y = -30

f(x) = x² is the quadratic parent function, Option B is correct.
What is a function?
A relation is a function if it has only One y-value for each x-value.
A parent function is the simplest function that still satisfies the definition of a certain type of function.
The quadratic parent function is the basic form of a quadratic equation and is written as f(x) = x².
This equation has no constants, no x-intercepts, and a vertex located at the origin.
All other quadratic equations can be derived from this basic form.
f(x) = x²- 5, f(x) = -4x² and f(x) = x² + 3 are not the parent functions but these are derived function after applying some rules.
Hence, f(x) = x² is the quadratic parent function, Option B is correct.

To find the mean, we divide to sum of all numbers in the data set by the number of numbers given,'8'.
(24+26+27+28+30+30+33+36)/8=234/8=29.25
Mean=29.25
To find the inter quartile range, we must solve for the lower and upper quartile mean.
Lower Quartile=(24+26+27+28)/4=26.25
Upper Quartile=(30+30+33+36)/4=32.25
32.25=26.25=6
Interquartile range=6
The median is the middle number in the data set, or the sum of the two middle numbers if there isn't a sole middle number
24,26,27,28,30,30,33,36
Median=(28+30)/2=29
Median=29
1st quartile we already solved for...
Lower/1st Quartile=(24+26+27+28)/4=26.25
3rd quartile we already solved for....
Upper/3rd Quartile=(30+30+33+36)/4=32.25
The mean would be most effected by an outlier of 52, the median would only go from 29 to 30.
