Theory of end behavior of the graph f(x)=a1xn+a2x(n-1)+ +an

When degree of the function is odd and leading coefficient is positive then graph will fall on the left and rises on the right.

When degree of the function is odd and leading coefficient is negative then graph will fall on the right and rises on the left.

When degree of the function is even and leading coefficient is positive then graph will  rise on left and right both sides.

When degree of the function is even and leading coefficient is negative then graph will  fall on left and right both sides.
