Help their can POSSIBLY be more than one correct answer 

### Homework Task **Problem:** (a) Sketch the function \( f = x^2 - 4 \). (b) Using the graphical method, determine the maximum number of roots this function has. **Choices:** - [ ] 2 - [ ] 1 - [ ] infinite - [ ] 0 **Instructions:** - Click "Submit" after selecting your answer. - You have 1 attempt. **Navigation:** - Home | (noPHP) - **Homework 10:** - Q1 Q2 Q3 - Q4 Q5 **Q6** - **Q7** Q8 Q9 - Q10 ### Graph Explanation The equation \( f(x) = x^2 - 4 \) is a quadratic function. A plot of this function will show a parabola that opens upwards with its vertex at the origin of the y-axis (\(x = 0, y = -4\)). **Key Points:** - The function intersects the x-axis at points \(x = 2\) and \(x = -2\), representing the roots of the equation. - Thus, the maximum number of roots for this quadratic function is 2, as shown by the intersections with the x-axis. Please proceed by sketching the function on a graph and identifying its roots.
