Graph by using its properties.

y=x2+8x+15

Short Answer

Expert verified

The required graph is:

Step by step solution

01

Step 1. Given information.

The given equation isy=x2+8x+15.

02

Step 2. Determine the parabola is open up or down.

Compare the given equation y=x2+8x+15with y=ax2+bx+c.

So, here a=1,b=8,c=15.

The value of the leading coefficient a=1>0.

So, the parabola opens up.

03

Step 3. Draw the graph.

The required graph is:
