Question

explain why the function is discontinous at the given number a. sketch the graph of the function

f(x) { e ^x if x < 0 / x squared if x > or = t 0} a= 0 how do i even start to solve this? does any one know how to solve step by step ?

Answer 1

at the point x=0 you jump from one curve to another
if x<0 then e^x (this will give you roots of e)
if x>=0 then x^2 (this is exponetial curve)
