F(x)=sqrt(x) a=1
My prof put (1/2)(x+1) as the answer, but I did not get that.
I used
F(a)+F'(a)(x-a)
1+(1/2)(x-1)
1+(1/2)x-(1/2)
(1/2)x+(1/2) is what I got. Am i doing something wrong?

No, you did it exactly right. Just factor your answer and you get what your prof did. To put it another way, expand your prof's answer. You get what you had.

looks right to me...
your answer is the same as your professors.
1/2 times x is 1/2x
1/2 times 1 is 1/2
therefore (1/2)(x+1)=(1/2)x+(1/2)
your answer is just as good as the profs

x = 1
(1/2) + (1/2) = 1
Not sure, but I think this is correct.

EDIT: Actually I just made this up. I put what I thought would work. I never learned approximation lol. But it looked perfect to me =D!

EDIT: Looks like I'm wrong.

yes, you worked correctly.
actually, it's the same thing, just factor the 1/2 from both terms
