Для функции у=f(x) найдите значения f(-1),f(0),f(1),f(2) помогите кто может
Y = f(x) 1) f(-1) = 4 - 0.5×(-1) = 4 + 0.5 = 4.5 f(0) = 4 f(1) = 3.5 f(2) = 3 2) f(-1) = 3×(-1) - 2 = -5 f(0) = -2 f(1) = 1 f(2) = 4 3) f(-1) = -1^2 + 1 = 1+1 = 2 f(0) = 1 f(1) = 1+1 = 2 f(2) = 4 + 1 = 5 4) f(-1) = 0.75 f(0) = 0.6 f(1) = 0.5 f(2) = 3/7
спасибо большое
