Answer:
D. 2(√{x} + √{x - 2})
Step-by-step explanation:
As hinted in the question, we have to simplify the denominator.
To understand it easier, let's imagine we have x - y in the denominator. If we multiply it with x + y we'll get x² - y², right? Check the next line:
(x - y) (x + y) = x² + xy -xy - y² = x² - y²
If we have the square of those nasty square roots, it will be much simpler to deal with. So, let's multiply the initial fraction using x+y, but with the real values:
Then we simplify:
Answer is D. 2(√{x} + √{x - 2})
Answer:
Option (1) increase.
Step-by-step explanation:
Let an exponential function is having common ratio = 3 ( greater than 1) and y-intercept = -1
So the function is,
Now we prepare a table for the values of x and f(x),
x -1 0 1 2
f(x) -1.67 -1 1 7
We find from the table that the values of the function are increasing with the increase in the values of x.
Therefore, Option (1) increase will be the answer.
