Use the graph of f(x)={x+3,x<−1−4x−2,x≥−1. The graph with X-coordinate marks -4, -2, 0, 2, 4 and Y-coordinate mark -4, -2, 0, 2, 4. There is function f which starts intersects y-axis at (0, -2), and the x-axis at (-0.5, 0), then it increases till (-1, 2) then decreases and intersects x-axis at (-3, 0).

Over what part of the domain is function f increasing?

A. x < −1
B. x ≥ 2
C. x ≥ −1
D. x < 2

your answer would be 10x - 1

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.
