Write a function of x\displaystyle {x} for each rule given. Hint: Order of operations matters here

a) Multiplies the input by 6 and then adds 3
f(x)=\displaystyle {f{{\left({x}\right)}}}=  

b) Adds 3 to the input and then multiplies by 6
f(x)=\displaystyle {f{{\left({x}\right)}}}=  

c) Divides the input by 9 and then subtracts 5
f(x)=\displaystyle {f{{\left({x}\right)}}}=  

d) Subtracts 5 from the input and then divides by 9
f(x)=\displaystyle {f{{\left({x}\right)}}}=
