HOE DO YOU SEE IT?Using the graph, is ∫ 0 5 f ( x )   d x positive or negative? Explain. To determine
If the integral 05f(x)dx is positive or negative where f(x) is shown in the graph as follows: Explanation

Since integration of a curve is the area under that curve, therefore, if the negative area is more under the curve than the positive area, then value of integration of f(x) is negative and if the positive area is more than the negative than the value of integral is positive
