PLEASE HELP ASAP!!! CORRECT ANSWERS ONLY PLEASE!!!For which intervals is the function increasing?

Select EACH correct answer.

Answers

Answer:  B. ( -∞ , 0)   and   C. (1, 2)

Step-by-step explanation:

The y-value is increasing between x = -∞ and x = 0.

The y-value is decreasing between x = 0 and x = 1.

The y-value is increasing between x = 1 and x = 2.

The y-value is decreasing between x = 2 and x = +∞


So, the y-value is increasing at ( -∞ , 0) ∪ (1, 2)

Decide whether Rolle's theorem can be applied to f(x) = x2 + 5 on the interval [0, 3]. If Rolle's theorem can be applied, find all value(s) of c in the interval such that f '(c) = 0.

Answers

Answer:

Step-by-step explanation:

it is continuous in [0,3]

f'(x)=2x which exists in (0,3)

f(0)=0²+5=5

f(3)=3²+5=14

f(0)≠f(3)

so Rolle's theorem can't be applied.

An electrician charges a one-time fee of $75 plus $25 for each hour of service. If h is the number of hours and t is the total amount billed to the customer, then the variables are related by the equation t = 25h + 75.Which variable is the independent variable?



A.T


B.
There is no relationship between the variables.


C.H

Answers

If you would like to know which variable is the independent variable, you can do this using the following steps:

t = 25h + 75
h ... the number of hours ... independent variable
t ... the total amount billed to the customer ... dependent variable

The correct result would be C. h.
