Problem 1, 2, and 3 deal with transformations of functions. In these problems, g is related one of the parent functions f. (look at handout on transformations of functions)
(a). Identify the parent function f. (b) Describe the sequence of transformations from f to g. (c). Sketch the graph of g. (d). Use the function notation to write g in terms of f.
1 g(x) = -|x + 4| + 5
3.
In problems 4 and 5, write an equation for the function described by the given characteristics.
4. The shape of f(x) = , but shifted six units to the left and reflected in both the x-axis and the y-axis.
5. The shape of f(x) = |x|, but stretched horizontally by a factor of 2 and shifted down 5 units.
6. Describe the end behavior of the graph of the polynomial function.
7. Find all of the real zeros of the functions with their multiplicities.
8. Find all of the real zeros of the function with their multiplicities.
9. Find all of the real zeros of the function with their multiplicities.
10. Determine if a real zero exists between the given numbers a and b.
; a = -3, b = -2 Hint: intermediate value theorem
