Question

If f(x)=√(x+3)) how do i set up f(x+Δx)

Answer 1

\[f \left( x+\Delta x \right)=\sqrt{\left( x+\Delta x+3 \right)}\]

Answer 2

i have no idea what i do with the delta sign

Answer 3

Let me know what you want to do.

Answer 4

simplify
I've just never had a delta sign so it has me confused on what i can do with it

Answer 5

\[\Delta x is a \small increment \in x\]
write x+delta x in place of x

Answer 6

so is √((x+Δx)+3) the simplest it will get?
