True and false math questions I always ask myself (asymptotes)?

the graph of a rational function will never cross its horizontal asymptote?


the graph of a rational function will never cross its vertical asymptote?


to find a vertical of the graph of a rational function, set the numerator equal to zero?


to find the y int. of the graph of a rational function set x = to zero?


to find the x int. of the graph of a rational function, set the denominator = to zero?True and false math questions I always ask myself (asymptotes)?

true, or it would not be called an asymptote

true, or it would not be called an asymptote





to find a vertical of the graph of a rational function, set the numerator equal to zero?


true





to find the y int. of the graph of a rational function set x = to zero?


true, just like what you would to to find the y-int of any function





to find the x int. of the graph of a rational function, set the denominator = to zero?


false, set the numerator to be 0.. a denominator of 0 has no meaning (you can't have a fraction with the denominator of 0).. so in other words you don't have to worry about the denominator of a radical function when finding the x-int
