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:
What are the steps to solve the equation:
What are the steps to solve the equation:
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
