Find the intervals on which the graph of f is concave upward, the intervals on which the graph of f is concave downward, and the inflection points. f(x)=x³-12x²+3x+5

Inspect the graph of the function to determine whether it is concave up, concave down or neither, on the given interval. A cube function, m(x) = - 4x³, on (-∞,0) On the interval (-∞,0), the function m(x) = − 4x³ is concave down. neither concave up or concave down. concave up.

Determine whether f is even, odd, or neither even nor odd.

Determine g(x + a) - g(x) for the following function. g(x) = -5x2 + 2x
