 * 1) x< (3/4)^(1/3) -3, x > -3 (the number in the parentheses can't be <0 because the exponent is odd), vertical asymptote x= -3 horizontal asymptote: y=3
 * 2) solve by substituting x with 0, answer is 1/256
 * 3) there is none!!! remember that if the degree of the numerator > degree of denominator then horizontal asymptote does not exist!
