Answer:

1. f(x)=x+7

2. f(x)=1.2x

Step-by-step explanation:

1. If f(x+5)=x+12, then substitute

t=x+5\Rightarrow x=t-5

Hence,

f(t)=(t-5)+12\\ \\f(t)=t+7

Now change t into x:

f(x)=x+7

2. If f(x-5)=1.2x-6, then substitute

t=x-5\Rightarrow x=t+5

Hence,

f(t)=1.2(t+5)-6\\ \\f(t)=1.2t+6-6\\ \\f(t)=1.2t

Now change t into x:

f(x)=1.2x
