Help with #7 ame:6. Explain why the curve f(x) = x' +x° + x³ + x +1 is always rising.7. Let f(x) = x³ +3x- 2.a In view of the fact that f(0) = -2 and f (1) = 2, why would you expect theequation r +3x-2 0 to have at least one real root?b explain why the graph of f has no horizontal tangent.c Why would you suppose it follows from part (b) that the equation r+3x-2 0has no more than one real root?MTH 1
