# For each given graph of f(x),sketch a graph of A(x), the area under function f(x)?

The graph should be the amount of the integral.

#### Explanation:

$1. {A}_{1} \left(x\right) \approx x$
graph{x [0, 5, -1, 5]}
$2. {A}_{2} \left(x\right) \approx {x}^{2}$
graph{x^2 [0, 5, -3, 25]}
$3. {A}_{3} \left(x\right) \approx {\left(x - 2\right)}^{2}$
graph{(x-2)^2 [0,4, -1, 4]}
