I need help for this question because I need to understand this topic!

You and your family decide to go on a camping trip. As long as it stays above 58°F, your baby brother will get to come along. The function T(x) represents the temperature in degrees Fahrenheit, where x is the number of hours you are at the campsite. It is supposed to be the coldest 3 hours after you arrive. Use T(x) = x4 – 2x3 + x2 + 27 to determine the lowest temperature tonight. Will your brother get to go on the trip?

Answer:

  yes, brother can go

Step-by-step explanation:

Apparently, you're not to think to deeply about this function. Rather, you are to take the question at face value. It is asking if the value of T(3) is more than 58.

Evaluation of polynomials is facilitated by writing them in "Horner form."

  T(x) = ((x -2)x +1)x^2 +27

  T(3) = ((3 -2)3 +1)9 +27 = (3 +1)9 +27 = 36 +27

  T(3) = 63

The coldest temperature is supposed to be 63 degrees, which is above 58 degrees. Baby brother can come along.
