Domain=(-$\infty$,$\infty$ ) Range={-2}
This function is a horizontal line going through the y-axis at point -2. The function stretches on indefinitely to the left and to the right. This means our domain is infinite in both directions. Domain=(-$\infty$,$\infty$ ) The function is a horizontal line. We can not use interval notation because there is only one number. We instead use set builder notations. Range={-2}
