DonT ANSWER IF YOU DONT KNOW

1. The function c(n) below relates the number of bushels of apples picked at a pick-your-own orchard to the final cost for the apples.
It takes as input the number of bushels of apples picked after paying an entry fee to an orchard and returns as output the cost of the apples (in dollars).
c(n)=20n+15
Which equation below represents the inverse function n(c), which takes the cost of the apples as input and returns the number of bushels picked as output?
A) n(c)=c+20/15
B) n(c)=c-15/20
C) n(c)=c+15/20
D) n(c)=c-20/15

2. In a polynomial division problem, the dividend does not have an x^2 term. When the problem is written in long division form, what should be the coefficient of the x^2 term in the dividend?
A) 2
B) 1
C) -1
D) 0

Answer 1

1. The answer is B. n(c) = c - 15/20

2. The answer is D.) 0

Answer 2

1. c(n)=20n + 15

y = 20n 15
20n = y - 15
n = (y- 15/20)

The answer is B. n(c) = c - 15/20

2. The answer is D.) 0
