Let y=√3x. Find the change in y, Δy when x=2 and Δx=0.3

Answer 1

My friend,

please let me know f(x) = √3x it means x is under the radical or √3 is coefficient of x.

it is not clear.

Answer 2

This is an arithmetic exercise!

And I assume you mean sqrt(3x).

y+Δy = sqrt(6.09)

y=sqrt(6)

Δy = sqrt(6.09)-sqrt(6)

Use your calculator!!!!
