If f(x) = −2(x + 3)(x + 5), complete the square and determine the minimum or maximum value of the function.
A) f(x) = (x + 4)2 + 2 and f(x) has a maximum value f(4) = 2.
B) f(x) = −2(x + 4)2 + 2 and f(x) has a minimum value f(4) = 2.
C) f(x) = (x + 4)2 + 2 and f(x) has a minimum value f(−4) = 2.
D) f(x) = −2(x + 4)2 + 2 and f(x) has a maximum value f(−4) = 2.

Step-by-step explanation: answer should be D

step-by-step explanation:

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.
