For f(x) to be a function, the value of x should not be repeated. That is no x value can be more then once.
So the required table is

And for g(x) , not to be a function, we have to repeat x value that is

The answer should be A and D
Answer:
13.8
Step-by-step explanation:
Recall the trigonometric ratios
Sine = Opposite over Hypotenuse (SOH)
Cosine = Adjacent over Hypotenuse (CAH)
Tangent = Opposite over Adjacent (TOA)
Now lets look back at the question
We are given an angle and its adjacent side length (11) and we need to find the hypotenuse
The hypotenuse and adjacent sides corresponds with the trig function cosine so we will use cosine to solve for x
( remember that cosine = adjacent over hypotenuse )

step 1 multiply each side by x

now we have 
step 2 divide each side by cos(37)

we're left with x = 13.77439
Our last step would be to round to the nearest tenth
We would get that the answer is 13.8
The algebraic expression would be that Quarters = 25 - W
Answer:
The new slope is 1
Step-by-step explanation:
The slope of any two points can be found by:

Finding slope of (3,7) (4,9)

Finding slope of (4,9) (5,11)

So, the slope of the line is 2
Now if slope is divided by 2, new slope will be:

So, The new slope is 1
