What is the range of the following function:<br> y = 2(5^x) - 1
Orlov [11]
<h2>Hello!</h2>

The answer is:

The range of the function is:

Range: y>2

or

Range: (2,∞+)

<h2>Why?</h2>

To calculate the range of the following function (exponential function) we need to perform the following steps:

First: Find the value of "x"

So, finding "x" we have:

y=2(5^{x}-1)\\\frac{y}{2}=5^{x}-1\\\\\frac{y}{2}-1=5^{x}\\\\Log_{5}(\frac{y}{2}-1)=Log_5(5^{x})\\\\x=Log_{5}(\frac{y}{2}-1)

Second: Interpret the restriction of the function:

Since we are working with logarithms, we know that the only restriction that we found is that the logarithmic functions exist only from 0 to the possitive infinite without considering the number 1.

So, we can see that if the variable "x" is a real number, "y" must be greater than 2 because if it's equal to 2 the expression inside the logarithm will tend to 0, and since the logarithm of 0 does not exist in the real numbers, the variable "x" would not be equal to a real number.

Hence, the range of the function is:

Range: y>2

or

Range: (2,∞+)

Note: I have attached a picture (the graph of the function) for better understanding.

Have a nice day!

What is the perimeter of a rectangle whose width is (x - 7) units and whose length is (3x + 10) units?​
FromTheMoon [43]

Answer:

The answer is "(8x + 6) units".

Step-by-step explanation:

Formula of perimeter is:

\to \bold{P=2 \text{(Length +width)} }

       =2((3x+10)+(x-7))\\\\=2(4x+3)\\\\= 8x+6

Which of the following number 1001,1002,1004 will be the sum of 994 and a 2 digit number
katrin [286]

The number that will be the sum of 994 and a 2 digit number is 1004 (option 3). Details about digits of numbers can be found below.

<h3>What is a 2-digit number?</h3>

A digit is the whole numbers from 0 to 9 and the arabic numerals representing them, which are combined to represent base-ten numbers.

A 2-digit number is any number between 10 and 99.

According to this question, 994 is said to be added to a 2 digit number to result into either 1001, 1002 or 1004.

  • 1001 - 994 = 7 (1 digit)
  • 1002 - 994 = 8 (1 digit)
  • 1004 - 994 = 10 (2 digit)

Therefore, the number that will be the sum of 994 and a 2 digit number is 1004.
