PLEASE HELP!

Decide whether the relation defines a function

y=

it is

Step-by-step explanation:

for every x≠13 the function maps each value of the domain (x) to only one corresponding value of the range (y)

yes it is a rational function.

Step-by-step explanation:

You can easily find out by graphing the function and using the vertical line test. If a vertical line drawn anywhere on the graph (except at vertical asymptotes where values are undefined)  intersects the graph at only one point, then the relation is a valid function.

(See attached for graph)

We can see that indeed a vertical line drawn at any point will cut the graph only at one point, hence it is a rational function.

constants mean the stopped points or the points on a graph that nothing is changing, hope this

step-by-step explanation:

y = i/2 xtnop + (3i/2 tnop+ 1)
