what is the value of the function y = 2x + 3 ⁢when x=−1 ?

a. 5

b. 2

c. 1

d. −5

select is a function or is not a function to correctly classify each relation.

title is a function is not a function
{(3, , , , 8)}

{(2, , , , 4)}

{(2, , , , 6)}

{(3, , , , 4)}

put x=-1 in the equation

y=2(-1)+3=1

for the second one,

last two are not functions, as 6 has two different outputs.

second has two outputs for 2

so only first can be a fiction.
