Question

How in the world do you solve this?

find the indicated limit, if it exists. lim x~>3+ (5-2x^2)

Answer 1

put 3 in x

Answer 2

Oh i feel stupid now

Answer 3

let x = 3+h, for some positive h, then simplify as h equals 0.

but since this is just a polynomial to start with .... its continuous on its domain and therefore its just the value at x=3
