Finding the inverse function:

We are given a function y = f(x). To find the inverse function, we exchange x with y in the original function, and then isolate y.

So

We are given the function:

f(x)=(x+7)^5

So

y=(x+7)^5

Changing x with y

x=(y+7_{})^5

Now, we have to isolate y. So

(y+7)^5=x

We can apply the fifth root to both sides. So:

\sqrt[5]{(y+7)^5}=\sqrt[5]{x}y+7=\sqrt[5]{x}f^{-1}(x)=y=\sqrt[5]{x}-7

Which expressions are equivalent to ? Check all that apply.
GrogVix [38]

Answer:

6.2+8.7+8.9x

Step-by-step explanation:

For expressions to be equivalent, they must simplify to the same lowest form. 8.9x+6.2+8.7 simplifies to 8.9x +14.9.

Each of the expressions below must simplify to 8.9x + 14.9 to be equivalent.

9x+6+9  = 9x + 15 NO

3.9+6.2+8.7x  = 8.7x + 10.1 NO

3.7+8.9+6.2  = 18.8 NO

6.2+8.7+8.9  = 23.8 NO

6.2+8.7+8.9x  = 8.9x + 14.9 YES

3.9+6.2x+8.7  = 6.2x + 12.6 NO

3.9x+8.7+6.2 = 3.9x + 14.9 NO
