Examine the following equation:
y = 2x^2 + 20x + 1
* What shape does the graph of this equation make? (Hint: You should be able to tell just by looking at the first term of the equation.)
* Does the graph open up or down (Hint: You should also be able to answer this just by looking at the first term of the equation.)

The equation describes an upsidedown parabola, opening down.
Plotting the graph yourself should help you visualize the situation. Words can be confusing.
