## Update the value of a function in Manim

The code below will update the function *V* = 3(*x* - 6)^{2} as *x* increases in value. Notice that the equation is a parabolic curve with independent variable *x* and dependent variable *V*. The whole graph actually cannot be fitted on the screen. To improve visibility, the equation was multiplied by a reduction factor whose value is embedded-hard into the equation.
