Question

What ordered pair is closest to a local minimum of the function, f(x)?

A. (-1, -3)
B. (0, -2)
C. (1, 4)
D. (2, 1)​

Answer 1

Answer: Choice D. (2, 1)

Reason:

See the screenshot below. I used GeoGebra to plot the points.

The sub group of points D, E, F form a bowl shaped region. Imagine a small parabola passing through these points. Point E is either the local min or very close to it. This is because point E is at the bottom of the bowl shape.
