Answer 1

Hello there!


x² < 49

First, start by finding the critical points of the inequality

x² = 49

Now take square root

x =
`\pm √(49)`

x = 7 or x = -7

x < -7 doesn't work in the original inequality, so this is not the answer.

x > 7 doesn't work as well

-7 < x < 7 works in general inequality

Thus, the answer is -7 < x < 7

Since they don't give these options there, we can pick option F - No solutions

Answer: F
