What is (f–g)(x)?
f(x)= –3x2
g(x)= –3x2+9x

Hello!

To find (f-g)(x), subtract g(x) from f(x):

f(x) = -3x²

g(x) = -3x² + 9x

(f-g)(x) = -3x² - (-3x² + 9x)

Distribute the negative sign:

(f-g)(x) = -3x² + 3x² - 9x

(f-g)(x) = -9x

answer: a

step-by-step explanation:

if xy ~ yz therefore xy would be the same length as yz

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.
