Consider function f(x) = (x2 – 4)2 where x is a real number. Then the function has A. only one minimum B. only two minima C. three minima D. three maxima

The correct answer is A. only one minimum.

The function $f(x) = (x^2 – 4)^2$ is a parabola with its vertex at $x=2$. The parabola opens upwards, so it has only one minimum point, which is at $x=2$.

The other options are incorrect because they state that the function has more than one minimum point.
