PLEASE PLEASE HELP
Two quadratic functions are shown.
Function 1:
f(x) = 3x2 + 6x + 7 Function 2:
x g(x)
−2 13
−1 7
0 3
1 7
Which function has the least minimum value and what are its coordinates?

Best ResponseYou've already chosen the best response.1you can find the minimum value of a quadratic function by using the formula b/2a if we assume that the equation is given in the form y=ax^2 + bx +c then, try to plot the values of the second function roughly on a graph paper or even a simple paper will do good with some estimation and then, you can get the answer

Best ResponseYou've already chosen the best response.1okay! no problem assume that we have a quadratic equation of the form y=ax^2 + bx + c now, compare the equation y=ax^2 + bx + c (we call it the standard equation) to the given equation, i.e. f(x) = 3x2 + 6x + 7 so we get a=3, b=6, c=7 now put the values of a abd b in the formula that i have specified in the above post if you want it's derivation, i can help you with it

Best ResponseYou've already chosen the best response.1i think this question here just require you to input "x" they already give they g(x) solution for various values of "x" so; when x=2 f(2)=3(2)^2+6(2)+7..=7 .and ....g(2)=13 when x=1 f(1)=3(1)^2+6(1)+7....=4 and ...g(1)=7 when x=0 f(0)=3(0)^2+6(0)+7..=7 ...and g(0)=3 when x=1 f(1)=3(1)^2+6(1)+7 ...= 16 and g(1)=7 so we compare to see which function has the least minimum value..

Best ResponseYou've already chosen the best response.0so function 1 has the least minimum value and its coordinates are 0,7 @LynFran
