Find the second term of this sequence? 3n^2-1

Step-by-step explanation:

We get the second term by just plug in 2 (instead of n) in the sequence formula:

second term = 3×(2)² - 1 = 11

(- 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 )
