A polynomial of degree 4 has zeros of x = 2, x = 4i and and f(-5) < 0

Write a function in factored form.

A polynomial of degree 3 has zeros of x = 2, x = -6i and f(0) < 0

Write the function in standard form.

Use the numerical representation of the function f(x) to answer the questions:
a) Use the table to find f (f(2). b) DON'T DO:find the equation and use that to find
f (f(2).

What is the range of f(x) ? What is the domain of f(x) ?

DON'T DO:Does this function have an inverse? Explain why. How can you tell if it were a graph?

What are the steps to solve the equation:

steps to solve?

DON'T DO:
what are the steps to solve this equation?

a) what is the zeros and their multiplicities

b) What is the degree?

c) Fill in the blank with <, > , = : “a” ____ 0

d) Find f(f(3))

e) Solve for x given f(x) =5

f) Solve for x given f(x) > 5

g) write down a possible equation for the polynomial.

DON'T DO:

the function f(x) is shown. Sketch

g(x) = 3f(x) -1

g(x) = 0.5f(x-1)

g(x) = 0.5 + f(3x)

g(x) = 7f(0.5x)

Sketch the function if a < 0, b = 2, and d = 1

Sketch the function if a > 0, b = 1, and
d = 2

How would you solve both graphically and algebraically
