To find the slope of the curve ( y = x^2 - 3 ) at the point where ( x = 1 ), you need to find the derivative of the function and then evaluate it at ( x = 1 ). The derivative of ( y = x^2 - 3 ) is ( \frac{dy}{dx} = 2x ).

Substitute ( x = 1 ) into the derivative:

( \frac{dy}{dx} = 2(1) = 2 )

So, the slope of the curve ( y = x^2 - 3 ) at the point where ( x = 1 ) is ( 2 ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
