Answer:
Yes, f is continuous on [1, 9] and differentiable on (1, 9).
Step-by-step explanation:
The natural log function is continuous and differentiable on its domain of (0, ∞). So, it is continuous on any closed interval contained within this domain.
The function satisfies the hypotheses of the Mean Value Theorem on the interval [1, 9].

They both show a proportional relationship… as they are linear
Answer:
12 2/3
Step-by-step explanation:
4 2/9 / 1/3 -- > 38/9 / 1/3 ---> 38/9 x 3/1 --> 38/3 --> 12 2/3
To know which of the following expressions are polynomials, let us look at the definition of a polynomial:
Polynomial is derived from poly- (which means "many") and -nomial (meaning "term"), so it says "many terms".
For an instance: 
is a polynomial, but 
is not a polynomial because it contains single term only.
We must keep in mind that in polynomial it can have variables, constants, and exponents but it can never have division by a variable.
Now lets, look at the
since it has got one term it can not be a polynomial.
: it has got <em>more than one term</em> therefore, <em>it is a polynomial. </em>
: again it has got just one term so it is not a polynomial.
: Since it has got <em>more than one term</em>, so again<em> it is a polynomial. </em>
