You can put this solution on YOUR website!
a) domain is all real numbers because 3x^2 can never be -1
b) there is no vertical asymptote because the domain is all real numbers.
c)since the degree of the expression in the denominator is one more than the degree in the numerator there is a horizontal asymptote at y=0
d)range: for y is between -5.263... and 2.275... (graphing calculator)
e) the graph is asymmetric.
f) x intercept (when y=0) :
12x-3/3x^2+1=0
12x-3=0 multiply each side by 3x^2+1
12x=3
x=1/4
You can find any other points you wish.
