Explanation:
The combined gas law states that the pressure of a gas is inversely related to the volume and directly related to the temperature. If temperature is held constant, the equation is reduced to Boyle's law. Therefore, if you decrease the pressure of a fixed amount of gas, its volume will increase.

What is a graph?</h3>
The graph is a visual representation of information. It is shown by the x and y-axis. The given equation is f(x)=x²+3.
In first case, f(x)=x²+3, x = − 3
f(x)=x²+3
= (− 3 ) ² + 3
= 9+ 3
= 12
f(x)=x²+3 = (− 2 ) ² + 3
= 4+ 3
=7
f(x)=x²+3
= (− 1 ) ² + 3
= 1 + 3= 4
Therefore, The graph is a visual representation of information. It is shown by the x and y-axis.
