Describe the end behavior and estimate the xand yintercepts for each function. Estimate to the nearest tenth when necessary.
y=2x^5+x^3

Math 
Reiny,
no estimation needed for yintercept, let x=0 then y = 0
for xintercept, let y = 0
2x^5 + x^3 = 0
x^3(2x^1 + 1) = 0
x = 0 or x^2 = 1/2
so x = ±1/√2
as x > +big, y >  big
as x >  big, y > +big
