[(-6 - ,,5)]
plot the points on a coordinate plain.
draw vertical lines through the graph.
if any of the lines passes through the relation on more than one point it is not a function.
if not, it is a function.
answer: it is a function
step-by-step explanation: the vertical line test is used to determine if a relation is a function. if there are 2 points when you draw the line, then it is not a function, because a function is linear and cannot be vertical. you can solve this question is simply by looking at the numbers, and you can see that every input (x-value) has one output (y-value), and that there are no x-values that are repeated. so, therefore, it would be a function.
use the vertical line test to determine if the relation [(...
