If you are just supposed to evaluate the a) f(0) and b) f(4) then you would just plug it in the equation.
f(0)=0^2 - 8*0 + 16
f(0)=0 - 0 + 16
f(0)=16
f(4)=4^2 - 8*4 +16
f(4)=16 - 32 + 16
f(4)=0
Feel free to comment any questions and if there is any additional context to the question please say so I can help with that.

A contractor wants to rent a wood chipper from Acme Rental for a day for $118 plus $11 per hour or from Bell Rental for a day fo
Helga [31]

Answer:

C(x) = 118 + 11 x -- Acme

C(x) = 128 + 9 x --- Bell

Step-by-step explanation:

Given

Acme:

Daily = 118

Hourly = 11

Bell:

Daily = 128

Hourly = 9

Required

Determine the cost function for both

The cost function can be determined using the following illustrations:

Daily Rate + Hourly Rate * Number of Hours

Represent the number of hours with x

So, we have:

For Acme:

C(x) = 118 + 11 * x

C(x) = 118 + 11 x

For Bell:

C(x) = 128 + 9 * x

C(x) = 128 + 9 x

maw [93]

Answer:

y = 2x - 3

Step-by-step explanation:

The negative recipricol is -1/(-1/2) = 2

Use point-slope equation:

y-y1 = m(x-x1)

x1 = 3, y1=3

y-3 = 2(x-3)

y-3 = 2x-6

<u>y = 2x-3</u>
