Question

Calculate the tangent line (attached)

Answer 1

f = x + sqrt (x)

Do you know how to take the derivative of a function?

Answer 2

yea, i know to put in the form of y = mx + b but i don't quite remember how to put in the form that he wants...

Answer 3

f' = 1/(2sqrtx) +1

Answer 4

oh, it is in the form y-y1 = m(x - x1) , with y1 moved over by addition.

Answer 5

so just find the slope at 9 and plug it in

Answer 6

not getting it right,,.

Answer 7

did you get 7/6 ?

Answer 8

nope.. lol
which equation did yu use to find that?

Answer 9

f = x - sqrt (x)
f' = 1 - 1/2 x^(-1/2)
then substitute in 9 for x

Answer 10

oooh.. solve for y.. alright

thankis

Answer 11
