Which part of f(x) = 2x3 + x-3 - 2 makes this NOT a polynomial function?
x-3, polynomial cannot have a negative exponent on the variable x.
Which part of a polynomial function that you look at to determine the degree of the polynomial?
The highest power or exponent of x
Evaluate f(x) = x3 when x = 3
27
When we write the following function in Standard form. Which term should be the leading/first term?
f(x) = 5 - 6x4 - 7x8 + 12x2 - 3x
-7x8
What is the degree of a linear function?
Degree of 1
Evaluate f(x) = x5 when x = -2.
-32
Which part of this function makes it NOT a polynomial function:
f(x) = 1/2 x2 - 3/x + 7 ?
-3/x
Which type of polynomial is a 2nd-degree polynomial function?
Then, provide an example.
Quadratic Function.
Example could be f(x) = x2 + x - 1
Evaluate f(x) = x3 - 2x2 -3x - 6 when x = 2
What is -12?
These are the four trends you identify intervals for when you describe the behavior of a polynomial.
What are increasing, decreasing, positive, and negative?
The powers on the x-values all need to be __________ for the function to be a polynomial function.
Positive integers zero and above
the degree and type of the function
f(x) = 12 + 8x3 + x2 - 7x
Third Degree and Cubic Function
Evaluate f(x) = x^3 - 2x^2 - 3x - 6 at x = -2
What is -16?
When is a square root sign OK in a polynomial function?
When the x is outside of it, not under it.
the leading coefficient for the function f(x) = 6x - 3x2 - 12x3 +18
-12
A function curves down and touches the x-axis exactly then curves back up again. This is the reason you would have to describe two different intervals on either side of that point, even though all the points around it are positive.
What is because zero is neither negative nor positive?
