Then we may perform successive transformations to get the above equation into the standard form y 2 = 4x 3 − g 2 x − g 3 (note that this transformation can only be made when the characteristic of the field is not equal to 2 or 3). The resulting coefficients are:
The four color theorem was not given a valid proof until 1976. Kempe's proof can be translated into an algorithm to color planar graphs, which is also erroneous. Counterexamples to his proof were found in 1890 and 1896 (the Poussin graph), and later, the Fritsch graph and Soifer graph provided two smaller counterexamples. [3]
Therefore, the graph of the function f(x − h) = (x − h) 2 is a parabola shifted to the right by h whose vertex is at (h, 0), as shown in the top figure. In contrast, the graph of the function f(x) + k = x 2 + k is a parabola shifted upward by k whose vertex is at (0, k), as shown in the center figure.
The graph of the logarithm to base 2 crosses the x axis (horizontal axis) at 1 and passes through the points with coordinates (2, 1), (4, 2), and (8, 3). For example, log 2 (8) = 3, because 2 3 = 8. The graph gets arbitrarily close to the y axis, but does not meet or intersect it.

The Colts’ defeat also meant that the 9-5 Houston Texans will make the playoffs as AFC South winners. Meanwhile, there is a fascinating battle developing for the No. 1 seed in the NFC.
The weather is getting colder, but the NFL playoff race is heating up. Here's the updated bracket, standings and clinching scenarios for Week 15.
[a] This means that the function that maps y to f(x) + J(x) ⋅ (y – x) is the best linear approximation of f(y) for all points y close to x. The linear map h → J(x) ⋅ h is known as the derivative or the differential of f at x. When m = n, the Jacobian matrix is square, so its determinant is a well-defined function of x, known as the ...
