What are the domain and range of the logarithmic function f(x) = log7x? Use the inverse function to justify your answers.

S_A_V [24]

Answer:

Step-by-step explanation:

Since log is defined by all positive real numbers

therefore domain is all positive real number that is ( 0,∞)

Range is given by real numbers

inverse of the given function is (10^x)/7

Whose domain is all real numbers and range is all positive real number

And since we know that domain of function and range of its inverse

& range of a function and domain of its inverse is same

which we are getting in the problem

so answer is justified

the nutrition facts label from a 12 oz can of soft drink is shown below. Note that a serving of the soft drink is defined as 8 o

Nataliya [291]

The correct answer is C. 65

Explanation:

The serving size of the soft drink is 8oz, besides this, the amount of sugar for this serving size according to the label is 26 grames. Now, to calculate the amount of sugar in 20oz, one of the simplest methods is to use a rule of three, because three values are known, and one is missing. The process is shown below:

1. Write the known values and use x to represent the unknown values

8 oz = 26 grames of sugar

20 oz = x

2. Use cross multiplication (this means multiply 8 x 6) and divide it into the remaining value

$x = \frac{26 x 20}{ 8}$ or x = 26 x 20 / 8

3. Solve the equation

$x =\frac{520}{8}$ or x = 520 / 8

$x = 65$
