Hey!

$\Large\boxed{\mathsf{The~domain~is~x!}}$

The domain of a function is the "input values". In other words the "input values" are the x-values. The "output values" are the y-values or in other words the range. In this case the input is x. We need to input x to so we can solve the expression f(x) = 5x².
