Derivative of y

Answer 14

@Abhishekjha can u?

Answer 15

yes i got

Answer 16

Now, At x-axis..... y=0

Answer 17

So, find coordinates of A

Answer 18

oh yes is it 0,3

Answer 19

I think its (3,0)

Answer 20

@Abhishekjha

Answer 21

U there?

Answer 22

dy/dx= 18(2x+ 3)^-2*2

Answer 23

YEP its dy/dx=-36(2x+3)^-2

Answer 24

Now find dy/dx when x=3

Answer 25

value of y comes?

Answer 26

Nope when x=3 then dy/dx=-1/9

Answer 27

So, the slope of line AC will be 9

Answer 28

opps dy/dx=36(2x+3)^-2

Answer 29

So, when x=3 dy/dx=1/9
Thus the slope of the line AC is -1/9

Answer 30

Now, can u find the equation of line AC

Answer 31

yes ,,,,

Answer 32

GREAT
