Question and answer
Can you state whether the parabola opens up or down and whether the Y coordinate of the vertex is the maximum or the minimum. f(x)=(x+3)(x+4)
f(x)=(x + 3)(x + 4) f(x) = x^2 + 3x + 4x + 12 f(x) = x^2 + 7x + 12 The parabola opens up and the vertex is the minimum . when x = -7/2 ,f(x) = -1/4 f(x) = (-7/2)^2 - 7/2*7 + 12 f(x) = -49/4 + 12 f(x) = -1/4 f(x) > = -1/4 .

f(x)=(x + 3)(x + 4)
f(x) = x^2 + 3x + 4x + 12
f(x) = x^2 + 7x + 12
The parabola opens up and the vertex is the minimum .
when x = -7/2 ,f(x) = -1/4
f(x) = (-7/2)^2 - 7/2*7 + 12
f(x) = -49/4 + 12
f(x) = -1/4
f(x) > = -1/4 .
