# limit value on functions

## limit value on functions

(OP)
How do I do this in Mathcad?

Example.:

f(x)=x^3+3 for x<10
g(x)=x     for x>=10

Then plot it to get one single value for one single parameter?

### RE: limit value on functions

f(x):if(x<10,x^3+3,x)

I am not very familiar with the condition notation in Mathcad...

Thanks, Greg...

### RE: limit value on functions

Does it work, that looks an awful lot like excel on second thoughts?

It works.  It is just like the Excel function.

if(cond, x, y)
Returns x if logical condition cond is true (non-zero), y otherwise
