Confirm that f and g are inverses by showing that f(g(x)) = x and g(f(x)) = x. f(x) = the quantity x minus seven divided by the quantity x plus three. and g(x) = quantity negative three x minus seven divided by quantity x minus one.

The prove is mentioned below.

Step-by-step explanation:

Here the given functions are,

We have to prove that: f(g(x)) = x and g(f(x)) = x.

Since

Answer with Step-by-step explanation:

We are given that

We have to confirm that f and g are inverses by showing that f(g(x))=x=g(f(x))

Hence, f(g(x))=g(f(x))=x

Therefore, f and g are inverses.

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
