Questions & Step-by-Step Solutions

What type of curves does the equation y = kx^2 represent?
  • Step 1: Identify the equation given, which is y = kx^2.
  • Step 2: Recognize that this equation is in the form of a quadratic equation.
  • Step 3: Understand that a quadratic equation typically represents a curve called a parabola.
  • Step 4: Determine the role of 'k' in the equation. If 'k' is positive, the parabola opens upwards. If 'k' is negative, the parabola opens downwards.
  • Step 5: Conclude that the equation y = kx^2 represents parabolas that can either open upwards or downwards based on the value of 'k'.
