Functions $f(x)$ and $g(x)$ are shown below:
$$f(x) = 3x^2 + 12x + 16,$$ $$g(x) = 2 \sin(2x - \pi) + 4$$
Using complete sentences, explain how to find the minimum value for each function and determine which function has the smallest minimum $y$-value.
How do I find the minimum value? Can anyone show me?
