# How do you find the domain and range of y - 3 = 1(x - 3)?

Because there are no restrictions on the value for $x$ the Domain, or input to the equation is the set of all Real Numbers or: $\left\{\mathbb{R}\right\}$
Because this is a linear transformation the Range or output of this equation is also the set of all Real Numbers or: $\left\{\mathbb{R}\right\}$
