B. The inverse of function B is y = x - 5 - 1
C. The expression of m in terms of P is m = p - 6.5
How to find the inverse of function B
B, function B is given as
y = x + 5 + 1
To find the inverse we solve for x
x = y - 5 - 1 interchanging the variables
y = x - 5 - 1
The inverse of function B is y = x - 5 - 1
C. the composite function is given as
m → function A → function B → 2p + 1
where function A is (m + 4) * 2 and function B is m + 4 + 2
((m + 4) * 2) + 4 + 2 = 2p + 1
(2m + 8) + 6 = 2p + 1
2m + 14 = 2p + 1
2m = 2p + 1 - 14
2m = 2p - 13
m = p - 6.5
