M the graph of the function g(x) is a transformation of the parent function f(x)=x² . which equation describes the function g? g(x)=x²+2 g(x)=(x−2)² g(x)=x²−2 g(x)=(x+2)²

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

a = 11 : 4

b = 38

c = 1 for every 6
