Given:f(x) = -3x2 - 2x + 4Problem:Determine the derivative of f(x) using the definition of a derivative. f ' (x) = lim f(x+h) - f(x) h h→0 f ' (x) = lim -3(x+h)2+(x+h)+4 - (-3x2-2x+4) h h→0 f ' (x) = lim -3(x2+xh+h2)-2(x+h)+4 - (-3x2-2x+4) h h→0 f ' (x) = lim -3x2+xh-3h2-2x-2h+4 + x2+2x-4 h h→0 f ' (x) = lim xh+h2+h h h→0 f ' (x) = lim h(x+h+) h h→0 f ' (x) = limx+h+ h→0 f ' (x) = x+
