Function Transformations:

Shifts on x, where x and k form a binomial, are horizontal shifts. If k is positive, it is a left shift. If k is negative, it is a right shift.

The constant final term of the equation acts in the opposite way. It will be a vertical shift, and positive will mean up, negative will mean down.

So here, where there is a positive horizontal shift of 2 and a negative vertical shift of 7, the function is shifted 2 units to the left and 7 units down.
