Answer:
D)
Step-by-step explanation:
Given:
Use Exponent Rule:
Use Addition Rule:
What is the value of x? The square root of 2x =4
2 answers:
The answer would be: x=8
Here’s how you solve it!
Square both sides to get 2x out of the square root. 4 squared is 16
2x=16
Then divide both sides by 2
X=8
Make sure to check your answer by adding the square root 2*8 =4
Then simplify and you get 4=4
Since 4=4 that means the answer is correct and you are left with your answer:
x=8

By applying the concept of the inverse of a function and <em>algebraic</em> handling, we conclude that the inverse of f(x) = (- 2 · x + 2)/(x + 7) is g(x) = (- 7 · x + 2)/(x + 2).
<h3>How to find the inverse of a function</h3>
In this question we have a <em>rational</em> function f(x) and finding its inverse consists in clearing x in terms of f(x). Prior any algebraic handling, we need to apply the following substitutions:
x · (y + 7) = - 2 · y + 2
x · y + 7 · x = - 2 · y + 2
2 · y + x · y = - 7 · x + 2
y · (2 + x) = - 7 · x + 2
By applying the concept of the inverse of a function and <em>algebraic</em> handling, we conclude that the inverse of f(x) = (- 2 · x + 2)/(x + 7) is g(x) = (- 7 · x + 2)/(x + 2).
