Select one: A. g(x) = x2 − 1
B. g(x) = x2 + 1
C. g(x) = 2x2 − 1
D. g(x) = 2x2
E. g(x) = 3x2 − 2

C

Step-by-step explanation:

plug the first point in (0), cancels out B, D, E bc g(x) doesnt equal to -1

now the two left are A and C, plug in 1, A doesn't work because 1^2-1=0, not 1

C works because 2(1)-1 = 2-1= 1

C

Step-by-step explanation:

We can see that the y int is -1 which eliminates B D and E.

Next we can test one of the equations by plugging in one of values from table.

From this we can see that C is correct.

m

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.
