# What is the end behavior of the function f(x)=2x^4+x^3?

End behaviour $x \to \infty \mathmr{and} - \infty , f \left(x\right) \to \infty$
It is an even even function, hence ts graph would rise to the right and rise to the left. Hence as $x \to \infty \mathmr{and} - \infty , f \left(x\right) \to \infty$
