b. f(x) = –√x + 3this is the correct answer

r(x)=-\frac{1}{50}x^2+14x

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

x=200,p=10

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

m=-\frac{1}{50}

now, we can use point slope form of line

p(x)=mx+b

now, we can plug values

p(x)=-\frac{1}{50}x+b

we can use point

x=200,p=10

and find b

10=-\frac{1}{50}\times 200+b

10=-4+b

b=14

now, we can plug it back

and we get

p(x)=-\frac{1}{50}x+14

now, we can find revenue

we know that

revenue = price*quantity

so, we get

r(x)=x\times p(x)

r(x)=x\times (-\frac{1}{50}x+14)

r(x)=-\frac{1}{50}x^2+14x

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

y=-\dfrac{1}{2}x+8

is for x = 0. substitute:

y=-\dfrac{1}{2}(0)+8=0+8=8

y-intercept is 8 → point (0, 8).
