Select the function that represents a parabola with vertex at (2,1) and y-intercept (0,3). Question 9 options: A) ƒ(x) = 1∕2(x + 2)2 + 1 B) ƒ(x) = 2(x – 2)2 + 1 C) ƒ(x) = 1∕2(x – 2)2 + 1 D) ƒ(x) = 2(x + 2)2 + 1

correct answer:

i^31 = -i

hope this !

let me know

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.
