Sofia used these steps to find the Inverse of function f. Step 1
f(3) = 3+1
given
Step 2
31 + 4
y =
8
change / () to y
Step 3
3y + 4
1 =
8
switch x and y
81
Step 4
II
3y + 4
multiply each side by 8
Step 5
81 – 4 = 3y
subtract 4 from each side
Step 6
241 – 12 = y
multiply each side by 3
Step 7
241 – 12 = 1-1()
replace y with 1-10)
Use this information to complete the statement.
Sofia made a mistake in step
She should have

a

step-by-step explanation:

the denominator cannot be the same as one of the factors.

8 denominator times 2 denominator = 16

and 7 numerator time 11 = 77

77/16= 77/16 ( they cannot be further simplified)

you divide them and then you get the answer i took this class this year

step-by-step explanation:

it's 100

step-by-step explanation:

22, 28, 34, 40, 46

b)   f(n) = 6n + 16

  n = what is the number of the row ( 22 would be row 1) so if we replaced n with 1, we would get 22

c)   the  14th  row will have 100 seats

(1)   (2)   (3)   (4)   (5)   (6)   (7)   (8)   (9)   (10) (11) (12) (13) (14)

22 | 28 | 34 | 40 | 46 | 52 | 58 | 64 | 70 | 76 | 82 | 88 | 94 | 100
