If the derivative of y=k(x) equals 2 when x=1 what is the derivative of(adsbygoogle = window.adsbygoogle || []).push({});

a. k(2x) when x = 1/2

b. k(x+1) when x=0

c. k(x/4) when x =4

I had two different ideas both seemed wrong

the first idea was to implore some type of chain rule so

a. 2*2=4

b. 2*1=2

c 2*1/4= 1/2

by saying the outside function would be 2 and then taking the derivative of the inside function, but you can't really do this so it seems wrong

the second idea seems even more wrong to simpliy before the derivative so that everything would come to be k(x) making a,b, and c =2

if someone could help me that would be great

thx
