The graph of f(x) = x2 is translated 7 units left and 5 units down. Which function represents this transformation? A f(x) = (x + 7)^2 + 5
B f(x) = (x -7)^2 + 5
C f(x) = (x + 7)^2 -5
D f(x) = (x -7)^2 -5

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.
