Multiple ChoiceBased on the end behavior which option best describes the leading term?negative coefficient, even degreenegative coefficient, odd degreenegative degree, odd coefficientnegative degree, even coefficient
- 4. Multiple ChoiceWhich of the following is a COMPLETE list of all possible Rational Zeros?
f(x) = x3 + 2x2 - 6x + 8±1, 8±1, 2, 4, 8±1, 2, 41, 2, 4, 8 - 5. Multiple ChoiceTo determine the number of possible negative real zeros using Descartes's rule of signs,
we need to evaluate f(-x).
If f(x) = -3x5+ 8x4 - 6x3 + 5x2 - 7x - 1.
Then these are the signs of the terms for f(-x):- + - + - -- - - - - -+ + + + + ++ + + + + - - 6. Multiple ChoiceUse Descartes's rule of signs to determine the number of possible positive real zeros for
