What is the vertex form of the function y = 3x2 - 12x + 17 ? A y = 3(x - 2)2 + 5
B y = 3(x - 2)2 + 17
c y = 3(x - 2)2 + 11
D y = 3(x + 2)2 + 5

Helppp m pleas

Answer: the correct answer is 10step-by-step explanation: let the number be n, then the expression becomes,then“twelve more than the quotient of a number and two, decreased by four” iswhen n=4,we substitute 4 whetever we see n to get,we simplify to obtain,we further simplify to get,therefore the correct answer is c.
