Sep 02, 2010 · Write a power function. Write a power function y = axb whose graph passes through (2, 4) and (6, 10). Substitute the coordinates of the two given points into y = axb. 4 = _a ( 2b_ Substitute 4 for y and 2 for x. 10 = _a ( 6b_ Substitute 10 for y and 6 for x. Solve for a in the first equation to obtain a = and substitute for a into the second ... ................
