Question

How do you find the domain & range of a trinomial?

I have this example problem here if you need:
y = -x^2 - 2x + 3

Answer 1

Answer:

the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.

Step-by-step explanation:

Answer 2

2(x-3)(x+1)

3*1=3
3+(-1)=2

x^2-3+1x+3
2(x-3)(x+1)
