How do you graph # f(x)=x^2+3#?
Calculate the vertex and the
Step 1. Your equation is almost in vertex form.
Re-write it slightly to get
We see that
Step 2. Find the vertex.
The vertex is at (
Step 3. Find the
Step 4. Find the
There are no
Step 5. Calculate a few more points.
Step 6. Draw your axes and plot the three points.
Step 6. Draw a smooth parabola that passes through the four points.
And you have your graph.
