Question

для функции у=f(x) найдите значения f(-1),f(0),f(1),f(2) помогите кто может

Answer 1

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
