The vertex form of a quadratic function is f(x) = a(x - h)2 + k. What is the vertex of each function? Match
function rule with the coordinates of its vertex
f(x) = 9(x - 5)2 + 6
Which coordinate matches the vertex ?

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.
