The function f(x) changes value when x changes from x0 to x0 + dx. find the approximation error . round your answer, if appropriate.

f(x) = x^2, x0 = 7, dx = 0.06

The answer to this question is a simple one.
First, you need this formula :
 (x0 + dx)^2
You need to substitute the values of the formula
Then,.
(dx)^2 = (0.06)^2

So the answer to this question is .0036

I hope my answer helped you in somehow.
