Question

Find the derivative of the function. MEDAL WILL BE REWARDED!
g(x)=sqrt(5-3x)

Answer 1

chain rule
know what that is ?

Answer 2

Yes what should I do? Im not 100% sure on how to use chain rule @hartnn

Answer 3

what is the derivative of sqrt x ?

Answer 4

1/2x^2?

Answer 5

1/2 sqrt x
isn't it ?

Answer 6

wait......yes that's it okay

Answer 7

so,
d/dx (5-3x) = 1/[2 sqrt (5-3x) ] times d/dx (5-3x)
so whats
d/dx (5-3x) ?

Answer 8

5

Answer 9

no....
derivative of constant = 0

Answer 10

so wait, I don't see how that's a constant...oh wiat nvm. Okay so our derivative is 0

Answer 11

no,
d/dx (-3x) = -3

Answer 12

ohh im so sorry I thought it was 5x-3 not 5-3x, okay I got -3

Answer 13

so,
d/dx sqrt (5-3x) = -3/[2 sqrt (5-3x) ]

Answer 14

okay, is that my final answer? or should I simplify?

Answer 15

no, final answer..

Answer 16

okay, thank you so much!

Answer 17

welcome ^_^
