NO CALCULATOR!
Find the zeros of the function f(x) = (x - 2)(x + 1)(x + 3)
Sketch a graph of your
equation. (Hint: what is
the end behavior of your
graph? What are the
zeros?)
NO CALCULATOR!
Find the zeros of the function f(x) = (2x + 1)(x - 2)(x + 4)
Sketch a graph of your
equation. (Hint: what is
the end behavior of your
graph? What are the
zeros?)
If a zero occurs more than once, this
is called multiplicity
Find the zeros of the function f(x) = (x-2)(x+1)2 and state
any multiplicity
Sketch a graph of your
equation. (Hint: what is
the end behavior of your
graph? What are the
zeros?)
