Best ResponseYou've already chosen the best response.0Two quadratic functions are shown. Function 1: f(x) = 4x2 + 8x + 1 Function 2: x g(x) −2 2 −1 0 0 2 1 8 Which function has the least minimum value and what are its coordinates? Function 1 has the least minimum value and its coordinates are (−1, −3). Function 1 has the least minimum value and its coordinates are (0, 1). Function 2 has the least minimum value and its coordinates are (−1, 0). Function 2 has the least minimum value and its coordinates are (0, 2).

Best ResponseYou've already chosen the best response.0now you need to find the coordinates of the minimum value of 4x^2 + 8x + 1 do you know how to do that ?

Best ResponseYou've already chosen the best response.04x2 + 8x + 1 = 4(x^2 + 2x + 1/4) = 4 [(x + 1)^2  3/4] so the minimum values is at the coordinates (1 , 4*3/4) = (1,3)

Best ResponseYou've already chosen the best response.0so compare this wit (1,0) and you'll see which has minimum value

Best ResponseYou've already chosen the best response.0 the second coordinate will give you the minimum value (because second cood is the value of the function)

Best ResponseYou've already chosen the best response.0So the answer is D? Correct?

Best ResponseYou've already chosen the best response.0No it cant be D because the coordinates re not (0,2)

Best ResponseYou've already chosen the best response.0compare (1,0) and (1,3) thats all you need do
