Determine the domain of the following graph:

Determine the domain on which the following function is decreasing.

The graph of y = |x| is the solid black graph below. Which function represents the dotted graph?

• y = |x + 5| - 5

• y = |x - 5| - 5

• y = |x + 5| + 5

• y = |x - 5| + 5

The graph of y = f(x) is the solid black graph below. Which function represents the dotted graph?

• y = f(x + 5) + 5

• y = f(x + 5) - 5

• y = f(x - 5) + 5

• y = f(x - 5) - 5

find f(2)

Find f(0).
