1. "function" is spelled incorrectly which I'm sure is a typo.
2. What is x? Is it a scalar (single value) or a vector/matrix/array? If it's not a scalar, then no, this is not correct.
3. While x*x is effectively squaring a scalar, why not square the value using an exponent?
4. This is minor, but stylistically, there's no need for the space between sqr and (x).
5. Instead of asking if it's correct, test it!! Provide a wide variety of inputs including large numbers, small numbers, negative numbers, 0, etc.
