What is the domain function of -3(x-5)+8

↝ Quadratic Function has the domain of all real numbers. (Even not given the specific domain.)

↝ The equation is a parabola with (5,8) as a vertex. We call the equation as vertex equation.

The domain of -3(x-5)+8 is all set of real numbers.

↝ Interval Notation ↝

Since the domain of the equation is set of all real numbers.

Therefore, the domain is x ∈ R or (-∞,∞) or -∞<x<∞

There of them work. Recall that the domain of quadratic function is all set of real numbers.
