Get it now? Try the above Range of a Parabola Calculator again if needed. Step 2: find the value of the coefficient a by substituting the coordinates of point P into the equation written in step 1 and solving. Let D be the diameter and d the depth of the parabolic reflector. where f is the focal distance which is the distance between the vertex V and the focus F.

The equation of a parabola with vertical axis and vertex at the origin is given by. Parabola Calculator is a free online tool that displays the graph for the given parabola equation. the problem now only consists of having to find the value of the coefficient a. Formula for the Focal Distance of a Parabolic Reflector Given its Depth and Diameter. Step 3: Finally, the parabola graph will be displayed in the new window. Step 2: Now click the button Submit to get the graph. We must enter the 3 coefficients a,b,c as a=3, b=-6 and c=-2. Step 1: use the (known) coordinates of the vertex, ( h, k), to write the parabola s equation in the form: y a ( x h) 2 + k. The procedure to use the parabola calculator is as follows: Step 1: Enter the parabola equation in the input field. Tip: When using the above Range of a Parabola Calculator for 3x²-6x-2 Since the Range contains all possible y- values the Range is [-5, ∞) This implies that the vertex is a minimum and therefore the parabola takes on any value greater than 5.
The Range is simply all real numbers greater or equal to -5 or simply y>=-5.Įxplanation: This parabola opens to the top since the leading coefficient 3 is greater than 0. Calculate with arrays that have more rows than fit in memory. Next, compute the y-coordinate of the vertex by plugging h=1 into the given equation: p polyfit( x, y, n ) returns the coefficients for a polynomial p(x) of degree. To find the Range we first compute the x-coordinate of the vertex Since ANY x value can be plugged into this equation (we have no fractions, radicals nor logarithms) we can conclude that the Domain is ‘all real numbers’.
