1. Is the relation a function and why or why not?
{(1, 2), (2, 3), (1, 6), (4,3)}

Its not a function, D

Step-by-step explanation:

its not a function because the x value, 1, repeats. input is x and output is y, so the input of 1 has more than one output.

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
