Can someone PLEASE help me?I need help on the following questions: I have teacherhints

Info:

You work for the BeeSwaks Candle Company and have already updated the Brick and the Egyptian candles . The volume of the the brick is measured by the equation x^3-x^2. The volume of the Egyptian candle was marked by the equation 7x^2.

When comparing the graphs of the production volumes, after X> 8, the production of the Brick candle is greater proportion than the Egyptian candle. This result was to be expected, since the function of the Brick candle is a polynomial of degree 3, and the function of the Egyptian candle is a polynomial of degree 2.The volumes are equal at (8,448).

For Brick Candle Egyptian Candle Bc= (x3_ x2) Ec=(7x2)=2x? the positive values are assigned and replaced in the function, the values are obtained Bc Ec 0 0 5.25 3 21 13.5 47.25 36 84 XO -Nmtoo 2 XO - Nm moro 75 131,25 135 189 220,5 257,25 336 336 425,25 486 10 675 525 When graphing both functions, we have the following cost curves Cost 800 700 Brick Candle Egyptian Candle 600 500 Candle Production 300 200 100 1 2 3 4 6 7 8 9 10 XUFor Brick Candle Egyptian Candle BC=X3- X?
