Find the intervals in which `f(x)=x^2+2x-5` is increasing or decreasing.

Explanation

To determine the intervals in which the function \( f(x) = x^2 + 2x - 5 \) is increasing or decreasing, we will follow these steps:

### Step 1: Find the derivative of the function
To find where the function is increasing or decreasing, we first need to compute the derivative of \( f(x) \).

\[ f'(x) = \frac{d}{dx}(x^2 + 2x - 5) = 2x + 2 \]
