Answer

The graph of is a downward-opening parabola with its vertex at , -intercepts at and , and a -intercept at .

Solution

  1. Write the quadratic function:
  2. Factor out from the quadratic and linear terms:
  3. Complete the square inside the parentheses. Recall that for we add and subtract :
  4. Substitute the completed square back into the equation:
  5. Distribute the negative sign:
  6. Identify key features of the parabola from the vertex form :
    • The vertex is at .
    • The coefficient of is negative, so the parabola opens downward.
  7. Find the -intercepts by setting :
    Use the quadratic formula:
    Thus,
  8. Find the -intercept by setting :
  9. To select the correct graph among the options, look for one that:
    • Has a vertex at .
    • Opens downward.
    • Intersects the -axis at and .
    • Intersects the -axis at .
The graph matching these features is the one that represents

When plotting the equation , you’re looking at a downward-opening parabola because the coefficient of is negative. The vertex can be found using the formula , which helps to locate the peak point of the parabola. In this case, it will yield a vertex at , and substituting that back into the equation will help determine the vertex’s y-coordinate.
To visualize the graph correctly, you want to plot the vertex and find the intercepts. The y-intercept occurs when , giving you the point . From this, you can sketch the curve that opens downward, showing that the graph has a maximum point at the vertex and intersects the y-axis at .
