Step-by-step explanation:
A function cannot have more than one x value with different y values. A vertical line means this happens infinite times. It is undefined.
let x be how far up the wall ladder reaches
by Pythagoras theorem
x^2+5^2=13^2
x^2 =(13^2)-(5^2)
x= square root of 144
x= 12 or x =-12(rej,x>0)
hence ladder reaches 12 foot up the wall
