Understanding the Table of Values
The table of values provided represents a linear function, which is a fundamental concept in mathematics. A linear function is a polynomial function of degree one, and it can be represented in the form of y = mx + b, where m is the slope and b is the y-intercept. In this context, the table of values shows Marco's progress as he is pumping gas into his car.
Analyzing the Table of Values
The table of values consists of several input-output pairs, which are used to represent the linear function. Each input-output pair is a point on the graph of the function, and by analyzing these points, we can determine the slope and y-intercept of the function.
| Input (x) | Output (y) |
|---|---|
| 0 | 0 |
| 1 | 2 |
| 2 | 4 |
| 3 | 6 |
| 4 | 8 |
Identifying the Initial Value
The initial value is the output value when the input is 0. In this case, the initial value can be determined by looking at the table of values. The input is 0, and the corresponding output is 0.
Calculating the Initial Value
To calculate the initial value, we can use the formula for a linear function, which is y = mx + b. Since the initial value is the output when the input is 0, we can substitute x = 0 into the formula to get:
y = m(0) + b y = b
Since the initial value is 0, we can conclude that b = 0.
Conclusion
In conclusion, the initial value is 0, which is the output value when the input is 0. This is a fundamental concept in mathematics, and it is essential to understand the table of values and how to analyze it to determine the initial value.
