Question

Find the line which is perpendicular to the graph of fx=x/(x+2) at x=2

Answer 1

find derivative, find slope

Answer 2

you can first find y by plugging in x

Answer 3

y=2/4

Answer 4

now you have x,y need slope using derivative and then you are set to go

Answer 5

y-y1=m(x-x1)

Answer 6

f'(x)=((x+2)(1)+(x)(1))/(x+2)^2

Answer 7

?

Answer 8

umm i use product rule give me a sec lol

Answer 9

f'(x) = 2/(2+x)^2
slope: 2/(2+x)^2
slope 2/(2+2)^2
slope = 1/8
perpendicular slope: -8
f(2) = 2/4 = 1/2
y = -8x +b
1/2 = -8 (2) +b
b = 9/2

y = -8x + 9/2

Answer 10

oops i mean - not +

Answer 11

i got -8/3 as my slope and my y=-8/3x+(35/6) is that even close?
