I'm having trouble with this question on my homework for Calc I, I was hoping I could get some help here.

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

should I just start assigning numbers? or just go by how it looks the equation will behave

Ok I think it means that the limit should approach some constant possibly

#

Give me a moment

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 🥹

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)
