Note that f is continuous on (−∞, 6) and (6, ∞). for the function to be continuous on (−∞, ∞), we need to ensure that as x approaches 6, the left and right limits match. first we find the left limit. lim x→6− f(x) = lim x→6− (cx2 + 7x) = next, we find the right limit. lim x→6+ f(x) = lim x→6+ (x3 − cx)

1. d.90

2. e. none of these (80)

3. a. 0

4. b. 6

5. e. none of these (10)

6. a. 5

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
