Answer:

The domain is {x:x is a real number}

The range is {y:y is only 4}

Step-by-step explanation:

The domain of the function is the values of x

The range of the function is the values of y

f(x) = 4 is represented graphically by a horizontal line // to x-axis from y = 4

Every point on the this line has different values of x but same value of y

ex: (-1 , 4)  , (5 , 4) , ( 0.1 , 4) , ................

So f(x) = 4 is called constant function

Erica ran 3 out of 8 Miles. Mariah ran 3 out of 4 miles. Who ran father?
Katen [24]
What you need to is find out how much 3/8 is, compared to 3/4. since 4 is half of 8 you have to multiply 3/4 by 2, which gives you 6/8. 6/8 is greater than 3/8, therefore Mariah ran farther

Classify the following functions as growth or decay: f(x) = 10 (6/7)^x, g(x)= 1/3e^x, h(x)=5e^-x, k(x)= -10(6/7)^x
Strike441 [17]

It is known that any exponential function with the form f(x)=a^x is an increasing function while a function of the form g(x)=a^(-x) is a decreasing function.

Furthermore, it a function h(x) is increasing, then the function -h(x) is decreasing. By analogy, if a function k(x) is decreasing, then -k(x) is increasing.

Now let's analyze the functions from the problem.

\text{ Let }f(x)=10\cdot(\frac{6}{7})^x

Since (6/7)^x is increasing and the multiplying factor of 10 is positive, then the function <em>f(x)</em> is also increasing.

Use these rules to find whether each function is increasing or decreasing.

Remember that increasing functions are used to represent growth while decreasing functions are used to represent decay.

The sum of two consecutive positive even integers is at most 14. List all possible pairs of integers.
anastassius [24]
Let X be the first number
there is a 2 numbers distance between each even number eg.2 ,4, 6, 8, etc.
So the 2nd number is X+2
The sum of the 1st and 2nd numbers = 14
X + X+2 =14
2X +2 =14
2X = 14-2
2X = 12
X = 12/2
X = 6
Therefore,
The first number i.e, X = 6
And the second number i.e, X+2 = 6+2 =8
******************************************************************************
This is the only positive pair in case of two consecutive numbers if the are even numbers but not consecutive there will be more pairs
12 + 2 = 14
10 + 4 = 14
8 + 6 = 14 (Already found)
