Question

fly) = -2Determine whether each relation is a function.+13. {(3,-8), (-9,1), (3, 2), (-4,1), (-11,-2)}for x = -534. Evaluate the function for the given value of x and write the input x andoutput f(x) as an ordered pair.

Answer 1

$f(x)=\text{ }\frac{2x+1}{3}$

For x= -5, you have to replace the value in the function

$f(-5)=\frac{2(-5)+1}{3}=-3$

This means that when x=-5, y=-3, you can write it as pair (-5,-3)
