FAQs on Coefficient of Variable Video Lecture - Mathematics (Maths) Class 10
| 1. What is the coefficient of a variable? |  |
Ans. The coefficient of a variable is the numerical constant that multiplies the variable in an algebraic expression. It determines the scale or size of the variable's impact on the expression.
| 2. How is the coefficient of a variable calculated? | |
Ans. To calculate the coefficient of a variable, you need to identify the term containing the variable and the numerical constant that multiplies it. The coefficient is then the value of that constant.
| 3. What does the coefficient of a variable represent in a linear equation? | |
Ans. In a linear equation, the coefficient of a variable represents the rate of change or slope. It indicates how much the dependent variable changes for each unit increase in the independent variable.
| 4. Can the coefficient of a variable be negative? | |
Ans. Yes, the coefficient of a variable can be negative. A negative coefficient indicates an inverse relationship between the variable and the expression. As the variable increases, the expression decreases.
| 5. How does the coefficient of a variable affect the shape of a quadratic function? | |
Ans. The coefficient of the quadratic term (variable squared) in a quadratic function determines the shape of the graph. If the coefficient is positive, the graph opens upward, creating a U-shape. If the coefficient is negative, the graph opens downward, creating an inverted U-shape.
