Here, We are not saying x can be less than -3 or equal to -3.
We're simply checking what is always true for all values of x between -3 and 9.
So, for example:
Try x = -2 → is x > -4? YES
Try x = 0 → is x > -4? YES
Try x = 8.9 → is x > -4? YES
So in the entire range from -3 to 9 (not including the endpoints), x > -4 is always true.
That’s why “x > -4” must be true.
Simple Rule:
- We only consider values that satisfy our constraint (-3 < x < 9)
- For ALL those valid values, x > -4 is always true
- That's why it "MUST be true"
Hope it is clear!

Tricky question and I can see how this is confusing. First, note that the question says must be true which to me a huge signal for Testing Cases. I'm going to reorganize the solution so that we're going small -> large left to right (like a number line).
KNOWN: -3 < x < 9
So this means that all real values of x must fit in that range. Let's test some cases in that range and see which answer choices we can eliminate! Start with some extremes in the range:
Test: x = -2.9999 (smallest end)
This is a legal value of x, which means that x doesn't have to be greater than 0. Eliminate A and D.
Test: x = 8.9999 (largest end)
This is a legal value of x, which means that x doesn't have to be less than 8. Eliminate B.
What is left? C and E
We could test something in the middle, but notice that from the smallest to the highest number in this list, everything is greater than -4. So it is true that x > -4. Note that it would also be true that everything in the list is greater than -5 or -6 or -1000 or -1 million and so on. The reason that C works is because the entire range of x is definitely greater than -4! Choose C!
Hope this helps!
