Hi Jordan, The fact you need to use here is that Here is a similar problem.
The technique is to divide the numerator and denominator by x. The numerator becomes
and the denominator becomes
As x approaches infinity 1/x approaches zero so the numerator approaches 3  0 = 3 and the denominator approaches 0  7 = 7. Thus as x approaches infinity the fraction (3x  8)/(4  7x) approaches 3/7. I hope this helps,
