    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).

    Function 1 quadratics like f(x) = 3x2 + 6x + 7 you can find the axis of symmetry from this equation -b/2a from coefficients ax^2 + bx+c so we see b is 6 and a is 3 -6/2(3) = -1 that is your x -so plug this back in you equation and it will give you y or f(x)
