no, it's not
Step-by-step explanation:
x=-3 is a vertical line that is parallel to the y-axis
this is a relation but it is not a function
to be a function, for every x value there can be only one y value
on the vertical line x=-3, when x=-3, y can be 0 or 1 or 2 or - 5 or any other number
y=x^2 is a function
if x=2, y=4
if x=-2, y=4 also
you can have different elements of the domain go to the same element in the range
you cannot have the same element in the domain go to different elements in the range
this is what you have with x=-3
-3 goes to any number in the range
in a function you can have "many to one" but you cannot have "one to many"
