Step-by-step explanation:
The domain of the rational function in discuss as in the task content is the set of all real number values.
<h3>What is the domain of a rational expression?</h3>
The domain of a rational function or expression is the set of all real values of x, except for that/those which render the function or expression undefined as the case may be.
However, in this scenario, the denominator of the rational function is constant and hence all X-values render the expression defined.
Ultimately, the domain of the expression is the set of all real number values of x.

Answer:
Vertex: (- 2, -1)
axis of symmetry: x= - 2
Step-by-step explanation:
f(x)=x^2+4x+3
f(x)=(x^2+4x+4)+3-4.......complete the square
f(x)=(x+2)^2-1...................write in vertex form
Answer:
54 square inches
Step-by-step explanation:
To find the surface area, you multiply the width by the length of one of the squares, then multiply that number by the number of squares in the diagram.
3 x 3 = 9
9 x 6 = 54
Hope this helps :)
