Question

f(x) = 1/x+2, what is f(3+h)?

Answer 1

f(________)
whatever goes in that blank will replace every single x in the function with that blank. So for example, if you have f(x) = 2x^2 -x, then
f(3) = 2(3)^2 - 3
f(x+5) = 2(x+5)^2 - (x+5)
f(something) = 2(something)^2 - (something)

So its the same thing with your problem, it just means replace x with 3 + h

Answer 2

Replace x with 3+h, and you're done.

Answer 3

So it would be 1/3+h

Answer 4

1/5+h

Answer 5

You only replace x with 3 + h, it doesnt make the 2 disappear suddenly.

Answer 6

Yeah I meant 1/5+h right?

Answer 7

yeah
