Verified answer
b = x-value of the vertex
c = y-value of the vertex
Good luck!
enable me discourage you extra considering the fact which you're no longer asking the ideal people right here. at the beginning people right here are not going to place their recommendations right into a maths issue Secondly you may no longer determine if their rationalization is mathematically ideal and you ought to get at a loss for words even further, Now for the encouragement section. Google quadratic purposes and you gets notes, education tests, quizzes, worksheets, and step-via-step factor from stable web content. you ought to use Yahoo too (Any seek engine)
b = x value of its vertex, and c =y value of its vertes
so b : shifted to + left or - right.
c shifted +up or down-
note (x-b) meaning b is positive
