I'm not entirely sure what the mean by increasing or decreasing on the interval...

agreene · Answer

i mean, it tends very slowly towards infinity in the x>0 direction (on both x and y) and towards -inf in the x<0 direction...

agreene · Answer

erg i said that wrong... im kinda tired sorry. its y=7 for all x=/= 0

stamp · Answer

Seems like everything is fine, when x > 0 the function is increasing and when x < 0 the function is decreasing. The function is continuous at all real x values. The graph confirms this analysis http://www.wolframalpha.com/input/?i=7x^2%2F%28x^2%2B4%29
