An exponential function will always dominate a power function.

Which of the following statements are correct? There may be more than one correct answer.
There is at least one mistake.
For example, choice (a)should be True.

The highest power of is 3 and this is degree of the polynomial and the coefficient of is 7 and this is the leading coefficient.

There is at least one mistake.
For example, choice (b)should be False.

Try again, read the definition of a polynomial on page 38.

For example, choice (c)should be False.

Try again, read the definition of a polynomial on page 38.

There is at least one mistake.
For example, choice (d)should be True.

The highest power of is 4 and this is degree of the polynomial and the coefficient of is -5 and this is the leading coefficient.

There is at least one mistake.
For example, choice (e)should be True.

In a polynomial the powers of must be positive.

There is at least one mistake.
For example, choice (f)should be False.

Try again, read the definition of a polynomial on page 38.

Correct!
  1. True The highest power of is 3 and this is degree of the polynomial and the coefficient of is 7 and this is the leading coefficient.
  2. False Try again, read the definition of a polynomial on page 38.
  3. False Try again, read the definition of a polynomial on page 38.
  4. True The highest power of is 4 and this is degree of the polynomial and the coefficient of is -5 and this is the leading coefficient.
  5. True In a polynomial the powers of must be positive.
  6. False Try again, read the definition of a polynomial on page 38.
Consider the graph below, which gives a global view.
PIC
Which of the the following statements are correct?
Choice (a) is incorrect

Try again, the maximum number of turns is one less than the minimum possible degree.

Choice (b) is correct!

There are 4 turns so the minimum possible degree is 5. Since it is an odd power and the graph tends to as the leading coefficient is negative.

Choice (c) is incorrect

Try again, the graph tends to as and there are 4 turns.

Choice (d) is incorrect

Try again, the graph tends to as

Consider the 4 graphs below, which gives global views of the functions, and match them to possible formulae.
Choice (b) is incorrect

Try again, has to be of even degree and has to be of odd degree.

Choice (c) is incorrect

Try again, some of the formulae do not match any functions. Try expanding the factors.

Choice (d) is incorrect

Try again, some of the formulae do not match any functions. Try expanding the factors.
