Question

How do you find the derivative of `y=(x^2 - 1) /( x+1)`?

Answer 1

The derivative is `1`

Explanation:

Start by simplifying the function.

`y = ((x + 1)(x - 1))/(x + 1)`

`y = x - 1, x != -1" "->` there will be a hole at `x = -1`

We can now differentiate this using the power rule.

`y' = 1`

Hopefully this helps!
