Of all the 8 parent functions, which ones have asymptotes? are they vertical or horizontal? how do you figure them out on a graph?

Linear function :Diagonal line > f(x)=x
Absolute value: “V” - shaped > f(x)=!x!
Quadratic function: “U” - shape   > f(x) = x^2
Cubic Function: Squiggle, Swivel    > f(x) = x^3
Square Root Function: Horizontal ½ of a Parabola  >f(x)= square root(x)
Exponential Function: Backwards “L” Curves > f(x)= f(x) = 2^x
Logarithmic Function: Upside Down “L” curve in 1st and 4th Quadrant
