WebApr 20, 2024 · If we find the minumum value of g(x) = 3x2 + 2x + 4cos(x), we have found the maximal possible − a. So we have g ′ (x) = 6x + 2 − 4sin(x), g ″ (x) = 6 − 4cos(x) > 0. g(x) is dominated by the quadratic term 3x2 for large x and g ″ is always positive, so solving g ′ (x) = 0 will find the x -value where g(x) becomes minimal.
