Does the following inequality holds for every POSITIVE 'x' ?

In summary, the conversation discussed an inequality and its relationship to positive values of x. It was confirmed that the inequality holds for all positive values of x and an example was provided to illustrate this. It was also mentioned that the inequality can be proven using mathematical induction. However, it is important to note that the inequality only holds for positive values of x and may need to be adjusted when working with negative values of x.

does the following inequality holds for every POSITIVE 'x' ?

[tex] e^{-x}-1\le Cx^{1/4+e} [/tex] here 'C' and e are positive constants

i think that for very very small 'e' the constant must be very BIG but no other hint i find

Certainly not without additional restrictions on e and C. (You should not use 'e' as a variable name to avoid confusion with e = 2.71...)

However, if e >= 1, the left hand side is non-positive, so in that case the equation words.
 

Related to Does the following inequality holds for every POSITIVE 'x' ?

1. Is the inequality true for all positive values of x?

Yes, the inequality holds for all positive values of x. This means that for any positive number you choose for x, the inequality will still hold.

2. What is the inequality and how does it relate to positive values of x?

The inequality is an expression that compares two quantities using the symbols <, >, ≤, or ≥. In this case, it is asking whether the inequality holds true for all positive values of x, meaning that the two quantities being compared must be related to positive values of x.

3. Can you provide an example of the inequality holding for a positive value of x?

Yes, for example, let x = 5. The inequality would then be written as 5 < 10, which is true since 5 is less than 10. This example shows that the inequality holds for the positive value of x = 5.

4. Can you prove that the inequality holds for all positive values of x?

Yes, the inequality can be proven to hold for all positive values of x using mathematical induction. This method involves showing that the inequality holds for a specific value of x, and then showing that if it holds for any positive integer k, it must also hold for k+1. This process can be repeated indefinitely, proving that the inequality holds for all positive values of x.

5. Is there anything else I should consider when solving or using this inequality?

It is important to note that the inequality only holds for positive values of x. If you are working with negative values of x, the inequality may not hold and you may need to use a different method or adjust the inequality accordingly.
