6. tell whether the relation is a function. explain your reasoning. {(-1, 7), (9, 4), (3, -2), (5, 3) , (9, 1)} if you know the rest of the answers pls let me know there is not more to the question show your work to get brainliest comments (3) u

It is a function because for each input value there is only one output value.

Because the triangle ABC is isosceles, the leg of the triangle has the same length. For example, the length of one leg is a, then the other leg is a too.

Input the numbers to pythagorean formula
a² + b² = c²
a² + a² = 8²
2a² = 64
a² = 64/2
a² = 32
a = √32
a = √16 × √2
a = 4√2

The length of each leg is 4√2 inches
