integral of 3-|x|

Solution

integral

3 - ∣ x ∣

Solution

3 x - \frac{x ∣ x ∣}{2} + C

Solution steps

\int 3 - ∣ x ∣ d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int 3 d x - \int ∣ x ∣ d x

\int 3 d x = 3 x

\int ∣ x ∣ d x = \frac{x ∣ x ∣}{2}

= 3 x - \frac{x ∣ x ∣}{2}

Add a constant to the solution

= 3 x - \frac{x ∣ x ∣}{2} + C
