Answer:

In order to sketch a parabola, one will typically use the y-intercept, the x-intercepts, and the vertex.

Step-by-step explanation:

In order to sketch a parabola, one will typically use the given equation in standard form, $y = ax^2 + bx + c$ , and:

The y-intercept – the point where the parabola crosses the vertical axis – by substituting 0 for all x values in the given equation and solving for y.
The x-intercepts – the points where the parabola crosses the horizontal axis – by setting the given equation equal to 0 (i.e., y = 0) and finding the factors (or roots).
The vertex – the point of symmetry where the parabola changes direction and curves up or down – by using $x=\frac{-b}{2a}$ to find the x-coordinate then plugging that value into the given equation to find the y-coordinate.
