A) graph y = 2(x − 5)2 − 8 by finding the vertex and x-intercepts. explain your work.

b) write the equation of a quadratic whose x-intercepts are
3/2 and 5.

c) write the equation of a quadratic with a parent of y = 4x2 and a vertex of (−5, 7).

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.
