<em><u>The polynomial that represents the difference between the cost of distributing by train and the cost of distributing by truck is:</u></em>

f(x) =  -0.04x^2 + 18x + 75

<em><u>Solution:</u></em>

<em><u>The cost of distributing by train can be modeled as:</u></em>

-0.07x^2 + 40x - 105

<em><u>The cost of distributing by truck can be modeled as:</u></em>

-0.03x^2 + 22x - 180

where x is the number of tons of product distributed

To find: Difference between the cost of distributing by train and the cost of distributing by truck

Difference = cost of distributing by train - cost of distributing by truck

Let f(x) = difference in cost between trains & trucks

f(x) = (-0.07x^2+40x-105) - (-0.03x^2 +22x - 180)

f(x) = -0.07x^2 + 40x -105 + 0.03x^2 -22x + 180

Combine\ the\ like\ terms\\\\f(x) = -0.07x^2 +0.03x^2 + 40x - 22x +180-105\\\\Add\ the\ like\ terms\\\\f(x) =  -0.04x^2 + 18x + 75

Thus polynomial that represents the difference between the cost of distributing by train and the cost of distributing by truck is found

astra-53 [7]
F(-3) would be -8, because you would use the first equation. f(2) would be 4 apparently cause theres no x after the 4, or in the equation of the 4. Hope this helps. Please rate, leave a thanks, and mark a brainliest answer(not necessarily mine). Thanks, it really helps! :D
