To graph the , we will follow three steps.
- Graph the related .
- Test a point not on the .
- Shade accordingly. If the point satisfies the inequality, we shade the region that contains the point. If not, we shade the opposite region.
Step 1
Let's draw the graph of the related function, which is y=x2−8x+2.
Step 2
Next, let's determine which region to shade by testing a point. For simplicity, we will use
(0,0) as our test point. Let's see if it satisfies the given inequality.
y≤x2−8x+2 0≤?(0)2−8(0)+2 0≤?0−8(0)+2 0≤?0−0+2 0≤2 ✓ Step 3
Since (0,0) produced a true statement, we will shade the region that contains the point. Also, note that the inequality is not strict. Therefore, the parabola will be solid.
