If f(x) = x (x+1), show that f(x +h)-f(x) = h(2x+h+1) If f(x, y) = x³ + 4xy2 + y³, show that f(ax, ay) = a³ f(x, y) Given f(x)=x²-x+1, find Given g(x) = f(2+h)-f(2) h 1 x2 If f(x) = 2x4+x³ -2x² + 5x - 7, find f(-2) and f(0). find g(x) - g(3) x - 3 If f(x) = x (x+1), show that f(x +h)-f(x) = h(2x+h+1) If f(x, y) = x³ + 4xy2 + y³, show that f(ax, ay) = a³ f(x, y) Given f(x)=x²-x+1, find Given g(x) = f(2+h)-f(2) h 1 x2 If f(x) = 2x4+x³ -2x² + 5x - 7, find f(-2) and f(0). find g(x) - g(3) x - 3
