Describe the end behavior and estimate the x-and y-intercepts for each function. Estimate to the nearest tenth when necessary.
y=-2x^5+x^3
no estimation needed for y-intercept, let x=0 then y = 0
for x-intercept, 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
