3. State the domain and range of each function. Explain your thinking.a.?(?) = 32?+ 8 1 [4 marks]b.?(?) = 5 cos(9[? 80?]) + 3 [3 marks]c. 2 log3 (?2 5) + 1 [4 marks] a.?(?) =3(2?+ 8)1 [4 marks]This is a transformation of the parent function g(x)=x.The generic form of the transformed function is f(x) = ak(x-d) +cIn our case f(x) = -3[(2(?+ 4)] -1; so a=-3, k=2, d=-4 and c=-1
