What is the equation of the function that is obtained from f(x)=x by shifting 1 unit to the right and 2 units down?

We start with f(x) = x.

If the graph of this function is shifted 1 unit to the right, then the new function will be g(x) = x - 1.

If the graph of this last new function is translated 2 units down, then its equation will be h(x) = x - 1 - 2, or h(x) = x - 3.

The desired quation is h(x) = x -3

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
