Use the definition of the derivative to find f(x)= 5x^2 +6x

Thank you s much in advance, an explanation or work would really help!

The formula is Y=27+72x-1.5x where x is time in minutes. I figured out that the time for the intake to be at a maximum is 24 minutes and the maximum intake is 891 grams. The question I can't figure iut is over what domain is this function valid? Explain why the function makes no sense outside of this domain. I am so confused. Thank you very much.

Lim x--> infinity

(X^2 +6x +8 ) / (x^3 + 2x + 1 )

Please help!

Please include instruments and procedures you would follow

Nitrogen-15

Gold-199

Potassium-38

Thanks so much(:
