Best ResponseYou've already chosen the best response.0I know that the formula for rate of change is \[y^2y^1/x^2x^1\] but I don't know why I keep getting 3.70. Another post said the answer is B, but I don't know how they got that answer.

Best ResponseYou've already chosen the best response.0But when I copy and paste the graph, it says: graph of quadratic function f of t having x intercepts at 6, 0 and 18, 0 and vertex at 12, negative 36 and passes through 3, 49.5 and 9, negative 27.25 So I've been using \[y^2 = 49.5\] \[y^1 = 27.25\] \[x^2 = 3\] \[x^1 = 9\]

Best ResponseYou've already chosen the best response.0or I guess the first two numbers should be opposite? I'm not sure.

Best ResponseYou've already chosen the best response.0I mean like y^2 = 27.25 and y^1 = 49.5

Best ResponseYou've already chosen the best response.1x1 and y1 go with month 3 x2 and y2 go with month 9

Best ResponseYou've already chosen the best response.1so, yes, y2 should be 27.25 and y1 should be (approximately) 49.5
