Answer:
(x) = 
Step-by-step explanation:
Let y = f(x) and rearrange making x the subject
y = 2x + 3 ( subtract 3 from both sides )
y - 3 = 2x ( divide both sides by 2 )
= x
Change y back into terms of x, hence
(x ) =

Answer:
∠ ACE = 40°
Step-by-step explanation:
The sum of the angles in a circle = 360°, thus
arc AE = 360° - (112 + 28 + 112)° = 360° - 252° = 108°
∠ ACE is half the difference of the intercepted arcs, that is
∠ ACE = 0.5( arc AE - arc BD) = 0.5(108 - 28)° = 0.5 × 80° = 40°
