What type of function is represented by the equation y = x^2?

• A. Linear function
• B. Quadratic function
• C. Cubic function
• D. Exponential function

Answer: (B)

The equation \( y = x^2 \) is classified as a quadratic function. Quadratic functions are polynomial functions of degree two, characterized by their standard form, which typically looks like \( y = ax^2 + bx + c \), where \( a, b, \) and \( c \) are constants and \( a \neq 0 \). In this case, the equation has the form where \( a = 1 \), \( b = 0 \), and \( c = 0 \). Quadratic functions are known for their parabolic graphs, which open upwards or downwards depending on the sign of the leading coefficient \( a \). Since \( a \) is positive in \( y = x^2 \), the parabola opens upwards. The vertex of the parabola is located at the origin (0,0), which is the minimum point of this function. Understanding the nature of a quadratic function allows us to differentiate it from other types of functions. Linear functions represent straight lines and have the form \( y = mx + b \), where \( m \) is the slope and \( b \) is the y-intercept. Cubic functions involve terms to the third degree, typically in the form \(

The equation ( y = x^2 ) is classified as a quadratic function. Quadratic functions are polynomial functions of degree two, characterized by their standard form, which typically looks like ( y = ax^2 + bx + c ), where ( a, b, ) and ( c ) are constants and ( a \neq 0 ). In this case, the equation has the form where ( a = 1 ), ( b = 0 ), and ( c = 0 ).
