The value of the given function f (x) is 10
What is the value of the given function ?
[tex]f (x) = \left \{ {{2 \text{ for x} < 3} \atop {x- 1 \text { for x } \geq 3} \right. \\\\[/tex]
Integrating the given functions,
[tex]\int\limits^5_1 {f(x)dx = \int\limits^3_1 2dx + \int\limits^5_3 (x- 1)dx[/tex]
[tex]\int\limits^5_1 {f(x)dx =2x + [\frac{x^{2}} {2} - x][/tex]
Applying the limits,
[tex]\int\limits^5_1 {f(x)dx =[2(3)-2(1)]+ [\frac{5^{2}} {2} - 5-\frac{3^{2}} {2} + 3][/tex]
[tex]\int\limits^5_1 {f(x)dx =[6- 2]+ [\frac{25} {2} - 5-\frac{9} {2} + 3][/tex]
[tex]\int\limits^5_1 {f(x)dx = 4 + 6[/tex]
[tex]\int\limits^5_1 {f(x)dx = 10[/tex]
The value of the given function on integrating using the limits is 10
What is integration?
- Integration is a technique for combining slices to discover the total.
- Finding areas, volumes, central points, and many other important things may be done with integration.
- When infinitesimal data are combined, notions such as displacement, area, and volume can be created.
- An integral assigns numbers to functions in a way that describes these concepts. Integration is the action of locating integrals.
- The integrals listed here are those that fall under the category of definite integrals, which can be thought of as the signed area of the region in the plane that is enclosed by the graph of a particular function between two points on the real line.
- Integration is a fundamental, crucial operation of calculus, along with differentiation.
