WebYou want to find a polynomial such that a given number of points lie on the graph. observe that every given point is a "condition" on your function. A polynmial of degree n is of the form. P ( x) = a n x n + ⋯ + a 0. and has therefore n + 1 degrees of freedom. So for n given points a polynomial of degree n − 1 should do the job.

WebHence, we can write our polynomial as such: f ( x) = a ( x + 1) ( x + 9) ( x – 4) Now, we can calculate the value of the constant a. We can do this by using another point on the graph. Typically, an easy point to find from a graph is the y -intercept, which we already discovered was the point (0. -4). WebAug 26, 2013 · To find the equations of the line: The line passes through (0, 2) hence the y-intercept is 2. In the equation f (x) = ax + b, b is the y-intercept hence the equation is now f (x) = ax + 2. To find x we use point A. We substitute 10 for f (x) and 2 for x. This means we now have 10 = 2a + 2.
