Answer:
the first equation is the total legs on one dog being added together with 2 other total dog legs. The second equation is the number of dogs multiplied by the total number of legs on one dog. Either way both equation show 3 dogs with 4 legs each.
In 5-4.7-2x+5/8 there is only one term containing a variable: -2x. The coefficient is the (negative) numeral -2.
First, replace f(x) with y . ...
Replace every x with a y and replace every y with an x .
Solve the equation from Step 2 for y . ...
Replace y with f−1(x) f − 1 ( x ) . ...
Verify your work by checking that (f∘f−1)(x)=x ( f ∘ f − 1 ) ( x ) = x and (f−1∘f)(x)=x ( f − 1 ∘ f ) ( x ) = x are both true.
