Hello there!
x² < 49
First, start by finding the critical points of the inequality
x² = 49
Now take square root
x = [tex]\pm \sqrt{49} [/tex]
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
I hope this help!
As always, it is my pleasure to help students like you.
