please help I will give a medal
Two quadratic functions are shown.
Function 1:
f(x) = 4x2 + 8x + 1
Function 2:
x 2 1 0 1
g(x) 2 0 2 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.0go the graph and if you got the calculator a ti84+ to be exact there will be a graph button and thats how you graph like he has above for the second part but also for the first part ill send a picture for you to understand

Best ResponseYou've already chosen the best response.1you can find the minimum value of the first one by completing the square to get the vertex form

Best ResponseYou've already chosen the best response.1f(x) = 4x2 + 8x + 1 f(x) = 4(x^2 + 2x) + 1 = 4(x + 1)^2 4 = 1 = 4(x + 1)^2  3 that's vertex form for a(x  b)^2 + c vertex is (b , c) so comparing with our result we see that at the vertex which is a minimum the coordinates are (1,3)

Best ResponseYou've already chosen the best response.1from the drawing you can see that the minimum is at (1,0) for function 2 so what is the correct option?

Best ResponseYou've already chosen the best response.0because its Function 1 has the least minimum value and its coordinates are (0, 1). i kmow my graph is slopy but im pretty sure its B

Best ResponseYou've already chosen the best response.1Function 1 has the least minimum value thats for sure   I'll recheck by graphing it on my calculator

Best ResponseYou've already chosen the best response.1Yes the minimum for Function 1 is at (1,3) so that makes it less than the minimum for Function 2.
