Answer: 350?
Step-by-step explanation:
664-36=628
628 divided by 2= 314 (cost of the washer)
314+36= 350
Hope this helps!
The domain of any step function is the set of all real numbers. The domain deals with the possible inputs for x. We can replace x with any whole number, decimal, fraction, etc and get some output for g(x).
To visually see this, graph g(x) using technology or on graphing paper. Then for every point on the graph, draw a corresponding point straight down or straight up until you reach the x axis. You'll find that the entire x axis gets shaded in to indicate that any x value is allowed.
We know that the parabola opens downwards because it has a negative leading coefficient.

Why the parabola opens downwards?</h3>
For any polynomial, the leading coefficient is the coefficient in the term where is the large exponent of the polynomial.
The sign of that coefficient will determine the end behavior of the graph of the polynomial.
For the case of the parabola, a positive leading coefficient means that the parabola opens upwards, while a negative leading coefficient will mean that the parabola opens downwards.
Now, if you look at our parabola:
g(x) = -(x + 1)^2 - 3
You can see that there is a negative sign, thus when we expand the parenthesis, we will end up with a negative leading coefficient:
g(x) = -x^2 - 2x + 1 - 3 = -x^2 -2x - 2
So we know that the parabola opens downwards.
