Question

If f(x) = (1)/(sqr(x-1))
Find:
(f(x) - f(2))/(x-2)

Answer 1

=1/sqrt(x-1)-1/(x-2)

Answer 2

\[((\sqrt{x-1}) - x - 1) / (x - 2)(x - 1)\]

Answer 3

That's what I came out with. How did you get your answer?

Answer 4

f(2)=1

Answer 5

Yea

Answer 6

(1/sqrt(x-1)-1)/(x-2)

Answer 7

@AJ01 you can simplify even more

Answer 8

OK, that's what I got so far

Answer 9

(1-sqrt(x-1))/(x-2)(sqrt(x-1)

Answer 10

My calculus book says:

(-1)/(sqr(x-1))(1+(sqr(x-1))

Answer 11

\[\frac{ \frac{ 1 }{ \sqrt{x-1} }-1 }{ x-1 }\]

Answer 12

Denominator is x - 2

Answer 13

@Mimi_x3 dude come here

Answer 14

ok sorry about that..... comment denominator

Answer 15

srqt(x-1)
