Which of the following describes a one-to-one function?
1 answer:
check the picture below.
bearing in mind that a one-to-one function must pass the horizontal line test as well as the vertical line test.
now, |x| is the graph of a letter V more or less, and that'd fail the horizontal line test.
the first piecewise function, has say 4 : x < 0, namely for all values before 0, "y" is a steady constant of 4, that will be a horizontal line and will definitely fail the vertical line test.
[[x]] is pretty much the "floor function", and you can do a quick google search on it, or do it in your calculator, it should have a floor function, but that one will definitely fail the vertical line test as well.

Answer:
The value of given expression is 3.8.
Step-by-step explanation:
Given:
We need to find the simplified value of given expression using y =14
Solution:
Now we will substitute y =14 we get;
Now using PEDMAS we will first solve the parenthesis we get;
Now we will solve the exponent function we get;
we know that;
So we can say that;
Now we will solve the multiplication operation.
Now we will perform addition operation.
And finally we will perform subtraction operation.
3.8
Hence The value of given expression is 3.8.
