Best ResponseYou've already chosen the best response.2ok... find the line of symmetry for function 1, the formula is \[x = \frac{b}{2\times a}\] the function has a = 2 and b = 8 so can you just calculate that to start

Best ResponseYou've already chosen the best response.2well not quite \[x = \frac{(8)}{4} = 2\] so knowing the line of symmetry, you should know that this is the value of x that gives the minimum value... so substitute x = 2 into function 1 and get a value

Best ResponseYou've already chosen the best response.2no in function 1, just replace x with the number 2 and calculate the value..

Best ResponseYou've already chosen the best response.2great so the mimimum for function 1 is at the point (2, 7) now look at the table for function 2... what is the minimum y value...?

Best ResponseYou've already chosen the best response.2these are the y values for function 2 y = 2, y = 3, y = 2 and y = 17 which one is the lowest..?

Best ResponseYou've already chosen the best response.2great so in function 2, the minimum is at the point (1, 3) y = 3 and remember function 1 has a minimum at (2, 7) y = 7 so compare the y values and decide which is lower...?
