(7, 4), (5, - 1), (3, - 8), (1, - 5), (3, 6) Determine whether the relation is a function. Explain pls

The given relation is not a function.

Step-by-step explanation:

A relation is any set of ordered pairs, which can be thought of as (input, output).

A function is a relation in which no two ordered pairs have the same first component (x-values or input) and different second components (y-values or output).

Given the following relation: {(7, 4), (5, - 1), (3, - 8), (1, - 5), (3, 6)}

There is an input value (x = 3) that has two corresponding outputs (y-values): y = -8 and y = 6.  

Remember that a function can only take on one output for each input.

It also helps to do the Vertical Line Test, which allows us to know whether or not a graph is actually a function.  If a vertical line intersects the graph in all places at exactly one point, then the relation is a function.  To use the vertical-line test, imagine dragging a ruler held vertically across the  graph from left to right. If the graph is that of a function, the edge of the ruler would hit the graph only once for every x -value.

Attached is a screenshot of the plotted points on a graph, where I performed the Vertical Line Test. The green line is the vertical line that contains two points that made the relation invalid as a function.

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
