The function can be represented as follows;
(s + t)(x) = 5x + 5
(s - t)(x) = -3x - 1
(s.t)(x) = 4x + 5
How to solve functions?
Function can be solved by using techniques of substitution.
s(x) = x + 2
t(x) = 4x + 3
Therefore,
(s + t)(x) = s(x) + t(x)
s(x) + t(x) = x + 2 + 4x + 3
s(x) + t(x) = x + 4x + 2 + 3
s(x) + t(x) = 5x + 5
(s - t)(x) = s(x) - t(x)
s(x) - t(x) = x + 2 - (4x + 3)
s(x) - t(x) = x + 2 - 4x - 3
s(x) - t(x) = x - 4x + 2 - 3
s(x) - t(x) = -3x - 1
(s.t)(x) = s(t(x))
s(t(x)) = (4x + 3) + 2
s(t(x)) = 4x + 3 + 2
s(t(x)) = 4x + 5
