Question

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?
Function 1 has the least minimum value and its coordinates are (−1, 4).
Function 1 has the least minimum value and its coordinates are (0, 7).
Function 2 has the least minimum value and its coordinates are (−1, 7).
Function 2 has the least minimum value and its coordinates are (0, 3).

Answer 1

@phi

Answer 2

@Mehek14 pls help

Answer 3

is it D?
The minimum value for the first function is 4 i think and the second function is 3 right?

Answer 4

hint:
a quadratic function is represented by a parabola in the x,y-plane, so the minimum value of a parabola is given by the y-coordinate of its vertex

Answer 5

Thanks i got it
