Question

Need help and answers please!! ):

Answer 1

Heya User,

QUE 1
  --> f(x) = 4x³ - 2x² - 2x - 2

---> Clearly, DEG(f(x)) = 3 = odd
---> And also, --> Co-eff = +ve

--> Hence, f(x) falls to the left and rises to the right.

Similarly,

QUE 2
  --> f(x) = 3x² - 3x + 1

---> Clearly, DEG(f(x)) = 2 = even
---> And also, --> Co-eff = +ve

--> Hence, f(x) rises to the left and rises to the right.

QUE 3
  --> f(x) = -14x^3 + 9x² - 2

---> Clearly, DEG(f(x)) = Highest power = 3

QUE 4
  --> f(x) = 7x² - 2

---> Clearly, DEG(f(x)) = 2

---> Here you go!!
