Answer 1

Answer:

$a = 2; \ d = 2; \ c=1; \ b=1$

Step-by-step explanation:

Two functions are inverse where their composition results in a variable only:

$f(g(x))=x$

So, we have to insert the right numbers in place of letters a, b, c and d, to fulfil this definition. Those value would be: $a = 2; \ d = 2; \ c=1; \ b=1$

Replacing these values, we have:

$f(x)=x+2$

$g(x)=1x-2=x-2$

Applying the composition $f(g(x))$:

$f(g(x))=\frac{cx-d+a}{b}$

We observe that with this values, these functions are inverse, because it composition results x.

$f(g(x))=\frac{1x-2+2}{1}=x$

Therefore, the values are $a = 2; \ d = 2; \ c=1; \ b=1$

Answer 2

F(x) = x + 1
          ------
            b

g(x) = cx - d


flip values of x and y in each equation, then solve for y:


x = y + a
      -------
         b

y = a - bx

x = cy - d

y = x + d
