Question 764576: Can someone please help me with this. It is due tonight before midnight and I am so confused.
Graph the function, state the domain and range: f(x)=4
Graph the relation, state the domain and range: x=(y+2)^2.
Mention any key points on the graphs, including intercepts, vertex, or start/end points. Discuss the general shape and location of each of your graphs. State the domain and range for each equation, write them in interval notation. State whether each of the equations is a function. Select one of the graphs and assume it has been shifted 3 units upward and 4 units to the left. Discuss how the transformation effects the equation by rewriting the equation to incorporate those numbers.
This is making me stressed by the minute. Can someone please help me with this. I would surely appreciate it.

Question 764645: So frustrated and running out of time. My question was partly answered earlier but still confused. I have stressed too much over these equations.
I need to graph two different equations with at least five points to graph, show all math work for finding the points. The equations are:
f(x)=4 must find the domain and range of this function
x=(y+2)^2 must find domain and range of this relation.
Specifically mention any key points on the graphs, including intercepts, vertex, or start/end points. Discuss the general shape and location of each of your graphs.
