FAQs on Linear Functions Video Lecture - Mathematics for Digital SAT
| 1. What is a linear function? |  |
Ans. A linear function is a mathematical function that can be represented by a straight line graph. It has the form f(x) = mx + b, where m is the slope of the line and b is the y-intercept.
| 2. How do you determine the slope of a linear function? | |
Ans. The slope of a linear function can be determined by looking at the coefficient of x in the function's equation. The slope is equal to the coefficient of x.
| 3. What is the significance of the y-intercept in a linear function? | |
Ans. The y-intercept of a linear function represents the value of the function when x = 0. It is the point where the graph of the function intersects the y-axis.
| 4. How can you identify if a function is linear or not? | |
Ans. To determine if a function is linear, you can check if it can be written in the form f(x) = mx + b, where m and b are constants. If the function follows this form, it is linear.
| 5. How can linear functions be used in real-life applications? | |
Ans. Linear functions can be used to model relationships between variables in various real-life scenarios, such as calculating costs, predicting sales trends, or analyzing growth rates.
