: There are no real roots (the parabola never crosses the x-axis). 2. Determine Parabola Direction Look at the coefficient : The branches of the parabola point upward ( If : The branches point downward ( ∩intersection 3. Sketch and Identify Intervals Draw a simple x-axis and mark your roots ( ). Sketch the parabola based on its direction. For >is greater than 0 , look for the parts of the graph above the x-axis. For , look for the parts below the x-axis. 📖 Example: Task 304 (j) The specific problem is a common variant in this set. Find Roots : Direction : Since (positive), the parabola opens up . Intervals : The function is positive outside the roots. Answer : 💡 Best Online Resources
