So I'm working on this assignment but I'm not really sure how to get the value of $x$. I'm confused in getting the value of $x$. I just want to know how to get it so I can determine the truth value of it.
Let $P(x)$ be the statement $x^3+5x\le6$. Determine the truth value of each proposition:
- $P(0)$
- …
I didn't put all the problems since I just want to know how to get that value, not the answer directly.
