(ax+b) find the derivative

Answer 1

heya user
suppose y=(ax+b)
then it's derivative will be
dy/ dx=a

hope it helps you....
for further query comment

Answer 2

Answer:

f'(x)=a2√ax+b

Explanation:

differentiate using the chain rule

Reminder ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯∣∣∣22dydx=dydu×dudx22∣∣∣−−−−−−−−−−−−−−−−−−−−→(A)

let u=ax+b⇒dudx=a

⇒y=u12⇒dydu=12u−12

substitute into (A), changing u back into terms of x

⇒dydx=12u−12.a

=a2√ax+b
