**Use this figure to find the following definite integrals:**

**Description of the Graph:**

The graph presents a curve labeled \(y = f(x)\), and the x-axis and y-axis are shown. Three distinct regions are shaded under the curve, each indicating different definite integrals. 

- **Yellow Region**: 
  - Located above the x-axis.
  - Bounded between x-values labeled \(0\) and an unlabeled point, presumably positive.
  - The area of the yellow region is marked as \(12\).

- **Blue Region**:
  - Located below the x-axis, indicating a negative integral.
  - Bounded between x-values labeled \(a\) and \(b\).
  - The area of the blue region is marked as \(6\).

- **Orange Region**:
  - Located below the x-axis.
  - Bounded between x-values labeled \(b\) and \(c\).
  - The area of the orange region is marked as \(11\).

These regions can be used to calculate definite integrals over different intervals by considering the areas above and below the x-axis, with areas below indicating negative contributions to the integral.

### Understanding Definite Integrals

A definite integral is represented in the following forms, where \( f(x) \) is the function being integrated, and \( a \), \( b \), \( c \) are the limits of integration:

1. \(\int_{0}^{a} f(x) \, dx\)
2. \(\int_{0}^{b} f(x) \, dx\)
3. \(\int_{0}^{c} f(x) \, dx\)
4. \(\int_{b}^{a} f(x) \, dx\)
5. \(\int_{c}^{a} f(x) \, dx\)

These integrals are used to calculate the area under the curve \( f(x) \) from one limit to another on the x-axis. The notation \(\int\) is an integral sign, \( dx \) indicates integration with respect to \( x \).

### Detailed Explanation

- **\(\int_{0}^{a} f(x) \, dx\)**: This calculates the area under \( f(x) \) from \( x = 0 \) to \( x = a \).
- **\(\int_{0}^{b} f(x) \, dx\)**: This calculates the area under \( f(x) \) from \( x = 0 \) to \( x = b \).
- **\(\int_{0}^{c} f(x) \, dx\)**: This calculates the area under \( f(x) \) from \( x = 0 \) to \( x = c \).
- **\(\int_{b}^{a} f(x) \, dx\)**: This calculates the area under \( f(x) \) from \( x = b \) to \( x = a \). It may result in a negative value if \( b > a \).
- **\(\int_{c}^{a} f(x) \, dx\)**: This calculates the area under \( f(x) \) from \( x = c \) to \( x = a \).

These integrals are fundamental concepts in calculus, used extensively in science, engineering, and mathematics to solve various problems involving rates of change and areas.

Expert Solution
Step 1

The figure given in the problem represents the graph of the function y=f(x).

The region under the curve of the graph represents the values of a function between different integral.

The region about the x-axis is a positive region and the region below the x-axis is a negative region.

For 0afxdx,

From the graph, the value of the function in between 0 and a is 12.

So,

0afxdx=12

Thus, the value of the definite integral 0afxdx is 12.

For 0bfxdx,

From the graph, the value of the function in between 0 and a is 12 and between a and b is 6. As the region between a and b is below x-axis it is the negative region.

So, the integral will be the algebraic sum of values of both regions.

The value of integral is,

0bfxdx=12-6=6

Thus, the value of the definite integral 0bfxdx is 6.

Step 2

For 0cfxdx,

From the graph, the value of the function in between 0 and a is 12 (positive), between a and b is 6 (negative), and between b and c is 11 (positive).

So, the integral will be the algebraic sum of values of each region between 0 to c.

The value of integral is,

0cfxdx=12-6+11=6+11=17

Thus, the value of the definite integral 0cfxdx is 17.
