Which explicit rule represents the following arithmetic sequence: 7, 11, 15, 19,
1. an=3+4n
2. an=7+4n
3. an= 4+7n
4. an=7x4^n-1

The correct option would be A. an = 3 + 4n

You may test my substituting values in:

3 + 4(1) = 7

3 + 4(2) = 11

etc

29 is the correct answer

step-by-step explanation:

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
