Free points (answer something random) The function, f(x) = sec(x), is plotted below.

On a coordinate plane, parabolas repeat. A parabola opens up approaches StartFraction pi Over 2 EndFraction, has vertex (0, 1), and approaches StartFraction pi over 2 EndFraction. The parabola flips over the x-axis at every measure of pi.

For which values of x is the limit positive infinity when x approaches the values from the left?

Negative StartFraction 3 pi Over 2 EndFraction
Negative StartFraction pi Over 2 EndFraction
0
StartFraction pi Over 2 EndFraction
