we can use properties of functions to find this out
for ![f(x)=ax^b](https://tex.z-dn.net/?f=f%28x%29%3Dax%5Eb)
if b is even, then the ends of the function go in the same directions (both up or both down)
if b is odd, then the ends of the function go in different directions (one up and one down)
if a is positive and b is even, then both ends point up
if a is positve and b is odd, then it goes from bottom left to top right
if a is negative and b is even, then both ends point down
if a is negative and b is odd, then it goes from top left to bottom right
given ![f(x)=5x^4](https://tex.z-dn.net/?f=f%28x%29%3D5x%5E4)
a=5>0
b=4 which is even
so it has both ends pointing up
bottom right graph is yo answer
