All it takes for a relation to be a function is for each possible first number of a pair there's only one possible second number.

So if any of the sets has two pairs with the same first number, that one's not a function.

The last one has (3,2) and (3,5) so isn't a function.

Okay, First you subtract 0x to the other side:

0x-0x+2=1x-0x+3

2=1x+3

Subtract 3 on the other side:

2-3=1x+3-3

-1=1x

Whats the squareroot of 98

Taya2010 [7]

Answer: 7√2

Step-by-step explanation: To simplify a square root where the number inside the radical is not a perfect square like the square root of 98, we start by making a factor tree for the number inside.

98 factors as 2 · 49 and if you know your perfect squares,

you should be able to recognize 49 as 7 · 7.

What we are looking for in our factor tree

are pairs of factors that are the same.

If a factor pairs up, it will come out of the radical.

If a factor does not pair up, then it stays inside the radical.

So here, since our 7's pair up, a 7 will come out of the radical.

Since the 2 does not pair up, it stays inside the radical.

So our answer is 7√2.
