Is there an algebraic way to find this if the problem states: Define a function h by $\displaystyle h(x)=f(2x)$ where f is the function defined by $\displaystyle f(x)=x^2$, with the domain of f in the interval [-1,1].

a. Find the domain of h

b. Find the range of h

How would I find the range of h algebraically without creating a table?
