A function maps one input to one output. If an input maps to more than one output, the relation is <em>not a function</em>.
In order to make the mapping be <em>not a function</em>, you must show at least one member of set A being mapped to more than one member of set B. (It does not matter which input you choose, or which outputs you choose.) More than one member of set A may have multiple mappings.
In the attached diagram, I have mapped <em>1</em> to both <em>a</em> and <em>c</em> to make this be <em>not a function</em>.
Okay.

Answer:
m<B = 28°
Step-by-step explanation:
Given:
m<A = 112°
m<C = 40°
AC = 14
Required:
Find, m<B, AB and BC.
SOLUTION:
✍️m<B = 180° - (112° + 40°) (sum of ∆)
m<B = 28°
✍️Using sine rule, find AB.
Plug in the values into the equation.
Cross multiply
Divide both sides by sin(28)
(nearest tenth)
✍️Using sine rule, find BC.
Plug in the values into the equation.
Cross multiply
Divide both sides by sin(28)
(nearest tenth)
