a) f (x)=3-6x²+2x² - 1
b) f (x)=3x- x° – 5x²-1
c) f x)=-6x+x°+2x² – 1
3
d) f (x}=x+x°+2x² –-6
d) f (x)=x+X+.
4. Which polynomial function would have the ending behaviour : as x→∞,y→-∞ and as x→-o,y→-?
a) f(x)=7 x
° -8x* – 2x²+x²+3x-2
b) f (x)=- 7x° - 8x-
2x°+x+3x - 2
c) f(x)=-7x - 8x“ – 2x²+x²+3x-2
- 7x° - 8x
2x°+x+3x – 2
d) f(x)=7x° -8 x* -2x*+x²+3x- 2
