If f(x)=5x-3 which expression represents its inverse function?

Step-by-step explanation:

In order to find the inverse of a function  we need to follow  the given step

We shall do step by step to find the inverse of given function

Step(1) : we write f(x) =y

therefore here y =5x-3

Step(2)  Interchanging x and y

                 x =5y-3

                     or

                   5y-3 = x

Step :solving the obtained equation for y

                5y = x+3

                 y =

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.
