F(x) = 4x – 13
g(x) = 3x2 – 7x – 13
Find: f(g(x))

f(g(x)) = 12x²-28x-65

Step-by-step explanation:

hello :

f(x) = 4x – 13

g(x) = 3x² – 7x – 13

f(g(x)) =f(3x² – 7x – 13) =4(3x² – 7x – 13)-13

f(g(x)) = 12x²-28x-65

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.

answer: $201

step-by-step explanation: to get the answer, you first get 3 nieces that he sold and multiply it by 67 and get $201, so he earned $201 selling his nieces.
