Let f(x)= -3x^4+79x^2-3x+1
___________________
5x^4+19x^4+2x+5
Discuss the short run behavior for f(x)and the long run for f(x).

I think you meant to write 19x^3, not 19x^4, in the denominator
As x-> +infinity or -infinity, f(x) approaches an asymptote of -3/5
At x=0, it equals 1/5. In the region "near" x=0, there are some wild oscillations, and probably a few crossings of the x axis (where the numerator equals zero). There may be some singularities (infinities)in a negative-x region were the denominator is zero.
I suggest you do some plotting of the function yourself.
