What is the domain and range of y=6?

Answers

The domain is "what can I make x equal to, and still get a sensible answer. In this case the equation doesnt depend on x at all so the domain is "All real numbers."

The range is "what are all the sensible values the I can get as an answer for y". In this case we are told: "Y always equals six." So the range is just "Y=6".

Some other ways to wirte the same thing:

Domain: {x|x∈R}
Range: {y|y=6}

Domain: (-∞,∞)
Range: {6}
The domain should be
 (-∞, ∞) {y|y ∈ R}
And the range is:
{6}

Solve by using the perfect squares method.* x2 – 12x + 36 = 0

Answers

x^2 -12x + 36 = 0\n \n (x-6)^2= 0 \n \n x-6=0 \n \n x=6
x2 - 12x + 36 = 0 
x2 - 2*x*6 +6^2 = 0
(x-6)^2 = 0
x-6 = 0
x = 6
