the ternary operator render failed how to fix it?

[OriLiMu]

I follow the link, https://github.com/leonhma/obsidian-functionplot/wiki/Supported-function-syntax

Which say can have a condition on function like this:
condition ? expression1 : expression2. But not work for me how to fix it?

Here is my expression : 0<x<5?f(x)=-x^2+10x-15:f(x)=1

I ran into the same issue. The problem is that 0 < x < 5 doesn’t work in this syntax—you need to use a logical AND instead, like (x > 0) && (x < 5). Also, inside the ternary operator you don’t include f(x)=; just return the value.

So your expression should be:

f(x)=(x > 0) && (x < 5) ? -x^2 + 10*x - 15 : 1
