Worksheet: Predicting Graphs of Polynomials

Q1:

Determine whether the following statement is true: If the graph of a polynomial does NOT cross the π‘₯ -axis, then the degree of the polynomial is even.

  • A true
  • B false

Q2:

The given graph represents a polynomial function.

What can be said about the degree of this polynomial?

  • A The degree is exactly 4.
  • B The degree is at most 4.
  • C It is not possible to say anything.
  • D The degree is at least 4.

Q3:

Determine whether the following statement is true: If the graph of a function meets the axis infinitely many times, then the function is not polynomial.

  • A true
  • B false

Q4:

True or False: If the graph of a polynomial function has a maximum but no minimum, then the degree of the polynomial is even.

  • A True
  • B False

Q5:

Determine whether the following statement is true: If the degree of a polynomial is even, then its graph meets the π‘₯ -axis an even number of times.

  • Afalse
  • Btrue

Q6:

The graph of 𝑇 ( π‘₯ ) = π‘₯ ( π‘₯ + 1 ) ( π‘₯ βˆ’ 3 ) 2 meets the π‘₯ -axis at the points βˆ’ 1 , 0, and 3. The vertical lines, together with the π‘₯ -axis, divide the plane into eight regions (a)–(h).

In which regions does the graph of 𝑇 lie?

  • A (a), (b), (g), (h)
  • B (e), (f), (c), (h)
  • C (e), (f), (c), (d)
  • D (a), (b), (g), (d)
  • E (a), (f), (c), (h)

Q7:

Determine whether the following statement is true: If the graph of a polynomial meets the π‘₯ -axis an even number of times, then the degree of the polynomial is even.

  • A false
  • B true
