Question

EVALUATE. f(x)=sqrt(X+3)
f(x+triangle x)

Answer 1

We have
\[f(x)=\sqrt {x+3}\]
we need to find: \[f(x+\Delta x)\]
for that put \((x=x+\Delta x)\) in f(x)
\[f(x+\Delta x)=\sqrt{x+\Delta x+3}\]

Answer 2

Okay got that:)

Answer 3

Good:D

Answer 4

but is that it? @ash2326

Answer 5

yeah that's it, you just needed to find f(x+\(\Delta x\)), didn't you?

Answer 6

yes

Answer 7

do you mind helping me out with one more? similar to this? i can post here

Answer 8

yeah, then that is it.
Yeah, I'll help you , just close this one and post it as a new one
