Question

Which values are solutions to the inequality x^2 ≤ 36. A)6  B)7  C)3. D)36 E)39 F)no solution

anonymous · Answer

Let's solve your inequality step-by-step.
x2≤36
Let's find the critical points of the inequality.
x2=36
x=±36(Take square root)
x=6 or x=−6
Check intervals in between critical points. (Test values in the intervals to see if they work.)
x≤−6(Doesn't work in original inequality)
−6≤x≤6(Works in original inequality)
x≥6(Doesn't work in original inequality)
Answer:
−6≤x≤6
