Answer:
Step-by-step explanation:
In the first triangle, you have the following relation between a, b and h.
This is another form of the Altitude Theorem in a right triangle.
In the second example, we use the Altitude Theorem:
Let h denote the dotted line / the altitude;
h = 6, we take the positive version since we're in Euclidean Geometry.
Now we have to solve for x. It's easy since the h that we solved for is in a right triangle and we have Pythagora's Theorem for that.
It states:

Answer:
I assume that the function is:
Now let's describe the general transformations that we need to use in this problem.
Reflection across the x-axis:
For a general function f(x), a reflection across the x-axis is written as:
g(x) = -f(x)
Reflection across the y-axis:
For a general function f(x), a reflection across the y-axis is written as:
g(x) = f(-x)
Then a reflection across the y-axis, and then a reflection across the x-axis is just:
g(x) = -(f(-x)) = -f(-x)
In this case, we have:
then:
Now we can graph this, to get the graph you can see below:
