Given the following conic section, determine its shape and then sketch its graph.

Answers (1)

Step 1
We need to determine the shape of the given conic section using its equation.
Step 2
We know that, for the general equation of conic section
if \(\displaystyle{B}^{2}-{4}{A}{C}={0},\) then the conic must be a parabola.
For the given equation, \(\displaystyle{A}={1},{B}=-{2},{C}={1}\)
\(\displaystyle={0}=>\) given conic section is a parabola
Step 3
The graph of the parabola has been shown below.
