Question

Plaese help! been stuck on apex all day

Answer 1

It is
C. 
The leading coefficient is positive so the left end goes down.
And......
D.f(x) is odd so both ends go in opposite directions.

Answer 2

Ok, so it seems
erm

ok, even and odd
it is an odd one because the power is odd (3rd degree)
so then the ends go in different directions
and since leading coefient (5 in the 5x^3) is positive, it goes from bottom left to top right
so

A is false
B is false
C and D are true
answer is C and D
