The answer to your question is 14
11.99999998
volume of a cube=one side of the cube *3
reverse the operation to get 11.99999998
Use substitution:

The function
is piecewise continuous, since both <em>cx</em> ² and <em>cx</em> - 3 are polynomials. <em>f(x)</em> itself is continuous if both pieces meet at the same defined point. In other words, the limits of <em>f(x)</em> as <em>x</em> → 2 from either side have the same value of <em>f </em>(2) = <em>c</em>•2² = 4<em>c</em>.
We have
so in order for <em>f</em> to be continuous, we need
4<em>c</em> = 2<em>c</em> - 3 → 2<em>c</em> = -3 → <em>c</em> = -3/2
As the temperature may remain constant over some period of time or may change at every moment So a continuous graph will be the best way to show the temperature over 24 hour period.
So the answer should be
A continuous graph
