The expression 3x² represents
The expression 3x² represents a quadratic function, where 3 is the coefficient of the squared term and x is the variable. In this expression, x is squared, meaning it is multiplied by itself. The coefficient 3 determines the shape and orientation of the graph of the quadratic function. When graphed, the function would form a parabolic curve. The value of x can vary, and when it is substituted into the expression, the result will be a different value based on the value of x.
The expression 3x² represents a mathematical expression involving a variable, x, and an exponent of 2. This expression is called a quadratic expression because the variable, x, is raised to the power of 2.
To understand what this expression represents, we need to consider the operations involved. In this case, we have the variable x, which represents an unknown value. The exponent of 2 indicates that x is squared, or multiplied by itself.
To evaluate this expression for a given value of x, we substitute that value into the expression and perform the necessary calculations. For example, let's say we want to find the value of the expression when x = 4. We substitute 4 for x in the expression:
3(4²) = 3(16) = 48
So, when x = 4, the value of the expression 3x² is 48.
Overall, the expression 3x² represents a quadratic expression involving the variable x raised to the power of 2, and its value depends on the specific value of x that is substituted into the expression.
