Answer:
3x^2 + 3 --> 6, 15, 30, 51
2x^2 - 1 --> 1, 7, 17, 31
x^2 + 2 --> 3, 6, 11, 18
Step-by-step explanation:
Let's start with the first equation; 3x^2 + 3
Substitute 1 (the first digit in a sequence) for x.
3(1^2) + 3
3(1) + 3
3 + 3 = <u>6</u>
3(2^2) + 3 Then the second digit.
3(4) + 3
12 + 3 = <u>15</u>
Since the two numbers we have so far are 6 and 15, there is only one sequence this could match. 6, 15, 30, 51.
2(1^2) - 1
2(1) - 1
2 - 1 = <u>1</u>
This equation represents 1, 7, 17, 31.
These same steps apply to the other equation as well.
1^2 + 2, then 2^2 + 2, then 2^2 + 2, and so on. (But we don't need to do extra work to figure that out.)
There are many different combinations.
We just need two numbers that when you multiply them you get 12.
We can have:
Length = 1
Width = 12
Length = 12
Width = 1
Length = 2
Width = 6
Length = 6
Width = 2
Length = 3
Width = 4
Length = 4
Width = 3

Answer:
f^-1 (x)=x^2-4x+1
Step-by-step explanation:
y=sqrt(x+3)+2
x=sqrt(y+3)+2
sqrt(y+3)=x-2
y+3=(x-2)^2
y+3=(x-2)(x-2)
y+3=x^2-2x-2x+4
y+3=x^2-4x+4
y=x^2-4x+4-3
y=x^2-4x+1
