Neither. Since it can be either a minimum or a stationary point, we cannot say that it is a minimum. So the statement that "it is a minimum" is false. Consider the statement: "if x is not greater than zero, then x is less than zero" is false, because x can be equal to zero.

Isn't this the same question as this one? w-ww-.-jiskha.-c-om/display-.cgi?id=-1207258851 Err exactly the same. The min is wrong >.<. The minimum value occurs at x = -2 but the minimum value is not -2.

1) df/dx = 3x^2 -12 = 2(x+2)(x-2) There are critical points (where the derivative is zero) at x = +2 and -2. x=2 is a relative minimum. f(x) increases (when x increases) for x > +2 and decreases for -2 < x < 2 2) That equation has an absolute minimum at x = 4.

**Quadratic equations- word problem**

Yes, C(x) is the quadratic cost function, and the minimum is at the vertex. C(x) = 0.6x^2-0.8x+10.618 = 0.6(x^2 - 1.333x + 17.697) = 0.6 (x^2 - 1.333x +0.444 + 17.253) = 0.6 [(x- 0.667)^2 + 17.53] There is a minimum average cost when x = 0.667 hundred bikes (or 67 bikes). ...

That is an upward-concave parabola with only one horizontal tangent, which occurs at the minimum point. You can rewrite the function, by completing the square, as y = F(x) = 2(x^2 + 2x -6) = 2[x^2 +2x +1 -7] = 2[(x+1)^2 -7] Clearly, the minimum (and horizontal tangent) is at x...

Using positive integers, since 2008=8*251 and 16 = 8*2, 251x = 2y x=2, y=251 gives x+y=253 If you allow zero, then 0+0=0 is the minimum. now, if you allow negative integers, then there is no minimum value.
