## Exercise 1.16 - Solution

1. Graph the related quadratic function.
2. Test a point not on the parabola.
3. Shade accordingly. If the point satisfies the inequality, we shade the region that contains the point. If not, we shade the opposite region.

### Step

Let's draw the graph of the related function, which is

### Step

Next, let's determine which region to shade by testing a point. For simplicity, we will use as our test point. Let's see if it satisfies the given inequality.
Simplify

### Step

Since produced a false statement, we will shade the region that does not contain the point. Also, note that the inequality is strict. Therefore, the parabola will be dashed.
