Which input value produces the same output value for the
Tju [1.3M]

Answer: d)x=4

Step-by-step explanation:

<h3> The missing graph is attached.</h3><h3> And the options are:</h3>

a)x=-1\\b)x=0\\c)x=3\\d)x=4

By definition, a relation is a function if and only if each input value has one and only one output value.

It is important to remember that the input values are the values of "x" and the output values are the values of "y".

Observe the graph attached.

You can identify in the graph that the function f(x) and the function g(x) intersect each other at the following point:

(4,3)

Where the x-coordinate (input value) is:

x=4

And the y-coordinate (output value) is:

y=3

Therefore, you can conclude that the input value that produces the same output value for the  two functions on the graph, is:

x=4

HELP ME MARKING BRAINLEIST AND 20 POINTS
Reptile [31]

Chapter: States of Matter

Ans: Increases ( option a ).

Why ?

Explanation: As when the matter goes from solid to liquid, the process is done by gaining heat energy which results a transformation phase known as <u>melting</u>. Due to this, the particles in solid gain enough kinetic energy which starts random collision with each other, hence causes the expansion of intermolecular spaces.
