Question

The linear approximation at x = 0 to f(x) = (4 + 2 x )^(1/2) is y =

What am I suppose to use as a in the LA formula-> f(a)+f'(a)(x-a)

Answer 1

Linear approximation actually is just point- slope form!

Answer 2

What should you do if you want to find slope?

Answer 3

well I found the slope I just dont know what to use as x because you are suppose to use a value close to that. I tried .01 but it didnt work

Answer 4

Since they don't give the value a, we just get the equation!

Answer 5

at x = 0

Answer 6

I have the tangent line as y=1/2x+2

arent you supposse to pick a value for a thats close to 0?
or is it because its zero you dont have to pick a value?

Answer 7

If they give us other value close to tangency point!

Answer 8

Chlorophyll the Savior..!

Answer 9

so pretty much what they are asking for is just an equation

Answer 10

to the tangent line

Answer 11

Yep!

Answer 12

You think too far :P

Answer 13

I totally get it now! hahahaha you are telling me! I treat everything like a test in life, girls, homework, job. Its horrible! I can't stop! hahaha thank you so much for you help chlorophyll!

Answer 27

You are pretty quick idk! but so do I, I wish I was majoring in math I love this stuff!

Answer 28

No, it's not free! See how you are happy, it makes me sooo delightful :D

Simple I just learned it before you do!

Answer 30

In my country, we must come up on blackboard solve it everyday fast and smooth!
