Question

what does f '(1) stand for ?
i know f(1) just replaces the x in a equation... but what does the apostrophe in f '(1) mean?.....

Answer 1

it is inverse

Answer 2

replace x=1 in the inverse function of f

Answer 3

hmmm?? can u explain to me like in this equation?? x^2 - x +2

Answer 4

it is a bit difficult to explain through this but i will try

Answer 5

k ty =/

Answer 6

i will type the whole question... in case...
let f(x) = x^2 + ax + b. if f(1) = 6 and if f'(1)=-4, find the values of a and b and hence, find the local minimum point on y = f(x).

Answer 7

f'(1) ususally denotes the derivative when x=1

Answer 8

so f'(1) is just the derivitive of x^2 + ax + b?

Answer 9

f' is teh derivative of that, the (1) means you replace x by 1 as usual

Answer 10

ah ok, thx a lot ^.^
