What is the transformation of f(x)=- (x + 2)2- 4
pychu [463]

Answer: x=0

Step-by-step explanation: f(x)=(x+2)x2-4

                                               0=2x+4-4

                                                0=2x

                                                  0/2=0

                                             x=0

What is the slope OF THE GRAPH, not what is A slope, what is THE slope
Oksanka [162]

Answer:

-3/1

Step-by-step explanation:

The slope can be found by putting the rise over the run.  

Pick 2 points on the graph that intercept the line.

I'll pick (0,2), and (1,-1)

Look at the rise.(How many places it goes up or down)

The rise vertical distance(rise), between the two points is -3.

Now look at the run(the horizontal distance.)  It's 1.

Rise/Run =  -3/1  AKA -3
