Write an explicit formula for an arithmetic sequence whose common difference is -3, and first term is -9.

  an = -9 -3(n -1)

Step-by-step explanation:

The explicit formula for an arithmetic sequence with first term a1 and common difference d is ...

  an = a1 +d(n -1)

Putting your numbers into the formula gives

  an = -9 -3(n-1)

step-by-step explanation:

3024 rhe base is what up in worry about

(- 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 )
