Answer:

Step-by-step explanation:
The base function is given as

This graph opens up and has its vertex at the origin.
When we shift the graph of this function down by 9 units, its vertex is now at (0,-9)
The equation of this new graph is

33 in middle - and in between I
Answer:

Solution: x=-2
Step-by-step explanation:
Consider the equation
Plot the graphs of left and right side functions
and
as shown in the diagram. The solution of the equation is the x-coordinate of the point of intersection between those two graphs. As you can see these graphs intersect at point (-2,4), thus, the solution of the equation is x=-2.
