## How do you graph a parabola step by step?

Example 2: Graph: y=−x2−2x+3 y = − x 2 − 2 x + 3 .Solution:Step 1: Determine the y-intercept. … Step 2: Determine the x-intercepts. … Step 3: Determine the vertex. … Step 4: Determine extra points so that we have at least five points to plot. … Step 5: Plot the points and sketch the graph.

## How do you plot YX in Python?

Following steps were followed:Define the x-axis and corresponding y-axis values as lists.Plot them on canvas using . plot() function.Give a name to x-axis and y-axis using . xlabel() and . ylabel() functions.Give a title to your plot using . title() function.Finally, to view your plot, we use . show() function.

## How do you plot a smooth curve in Python?

Use scipy. interpolate. make_interp_spline to plot a smooth linex = np. array([1, 2, 3, 4])y = np. array([75, 0, 25, 100])plt. plot(x, y)x_new = np. linspace(1, 4, 300)a_BSpline = interpolate. make_interp_spline(x, y)y_new = a_BSpline(x_new)plt. plot(x_new, y_new)

## What is a parabola equation?

You recognize the equation of a parabola as being y = x2 or. y = ax2 + bx + c from your study of quadratics. And, of course, these remain popular equation forms of a parabola. But, if we examine a parabola in relation to its focal point (focus) and directrix, we can determine more information about the parabola.
