• First, you need to graph your functions so you can clearly describe the graphs in your discussion. Your
graph itself is not required in your post, although the discussion of the graph is required. Make sure you
have at least five points for each equation to graph. Show all math work for finding the points.
•Specifically mention any key points on the graphs, including intercepts, vertex, or start/end points.
(Points with decimal values need not be listed, as they might be found in a square root function. Stick to
integer value points.)
•State whether each of the equations is a function or not giving your reasons for the answer.
•Select one of your graphs and assume it has been shifted three units upward and four units to the left.
Discuss how this transformation affects the equation by rewriting the equation to incorporate those
numbers.
•Incorporate the following five math vocabulary words into your discussion. Use bold font to emphasize
the words in
?Function
?Relation
?Vertical Line test
?Transformation
The last letter of my last name is S. My first problem to solve is the following:
f (x)=4
f(x) is equal to y. When x is the input, f(x)=y is the output of the function f(x)=4. In this case,
f(x) = 4 can be written as y = 4.
To find the slope and y intercept, use the y= mx+b formula where m is the slope and b is the y
intercept. y = mx+b
Using the y =mx+b formula, m = 0 and b = 4.
m=0, b=4 where m is the slope and b is the y-intercept (x=0 and y axis =4)
My graph would look like this:
The red line shows how my line on my graph
looks. (0,4)
The domain of f(x)=4 is (-8,8),{x|x?R}(Allrealnumbers) and the range of f(x)=4 is {4}.
The domain is: (-8,8),{x|x?R} (All real numbers)
The range is: {4}
•State whether each of the equations is a function or not giving your reasons for the
answer.
•Select one of your graphs and assume it has been shifted three units upward and four
units to the left. Discuss how this transformation affects the equation by rewriting the
equation to incorporate those numbers.

My second problem is:
x=(y+2)2

I NEED TO SOLVE THE ABOVE EQUATION AND SHOW THE STEPS
My graph looks like this and the general area it is in is on the right hand side of the graph on the
lower half. The vertex is h, k (0,-2)
The domain of y=-4 is [0,8),{x|x=0} and the range of y=-4 is (-8,-4],{y|y=-4}.
The domain is: [0,8),{x|x=0}
The range is: (-8,-4],{y|y=-4}
