Hi, I just need a confirmation on the equation Y=Cosechx from -4 is less than and equal to X, which is less than and equal 4 is the same as
Y=e^4+e^-4 And that the value generated if equation was processed, supposed to generate the y value of 27.3?

Let' me supplement Subhostosh's comment with a

What??

That problem statement makes no sense. You seem to be asking how to define csch(x) in terms of exponentials but what are you doing with [math]-4 \leq x \leq 4[/math] and x = 4? And where did 27.3 come from?

Just for the record,−4≤x≤4, is read as x is between -4 and 4 inclusive
