#Limits and exponential function

You want the numerator to “outpace” the denominator
Therefore you need the denominator to essentially go to 0, stop growing, grow slower than the numerator, or help the numerator grow actually grow
im new to limits so I'm trying to understand. Because I tried to input 0 as a value for k and its said it was incorrect
how should I approach this problem numerically?
should I just start assigning numbers? or just go by how it looks the equation will behave
I’m attempting to read the question again and I’m unsure if the limit approaches infinity if that means the limit exists
Ok I think it means that the limit should approach some constant possibly
Give me a moment
Thank you so much
. I've been starring at this question for about an hour by now lol
Ok so for k values equal to or greater than ln2 will make the limit equal a constant which should make it exist
According to Google limits TECHNICALLY do not exist when they equal infinity so we are looking for e^kx > 2^x therefore the limit will not approach infinity
And will approach a constant
limit = 1 when k = ln2
limit = infinity (DNE) when k < ln2
limit = 0 when k > ln2
omg thank you so much I think I understand it better know and Just input the ln2 in the homework and It work. Thank you so much! I really appreciate your help! You're a life saver 🥹
Thank you so much really appreciate your help 🥹
Actually ignore my thought about greater than Ln2 means their is a limit I am unsure but u got it correct so I guess it works
e^kx = 2^x
kx=xln(2)
k= ln(2)
In case u wanted the work
Thanks again🥹 (thank you for the work I'll check it tomorrow when my brain is fully awake lol)
