Compare these two scenarios. which scenario, a or b, represents a function?

Scenario, A represents a function.

Step-by-step explanation:

The question is the missing the graph

See the attached figure.

A function is a relationship where each input has a single output.

So, according this definition we will test scenarios A and B

Scenario A :

As shown at scenario A, each value of the time (input) has a single value from the distance (output)

So, scenario, A represents a function.

Scenario B :

As shown at scenario B, there is a value of the height (input) has two values from the time (output)

the number 70 in. from the height has two values which are 54.6 and 53.11 sec

So, scenario, B dose not represent a function.

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
