Which description compares the domains of function a and function b correctly?
function a f(x) = log x
function b
a - the domain of function a is the set of real numbers greater than or equal to 1
the domain of function b is the set of real numbers greater than 1
b- the domain of function a is the set of real numbers is greater than 0
the domain of the function b is the set of real numbers greater than or equal to 1
c- the domain of both functions is the set of real numbers
d- the domain of both functions is the set of real numbers greater than or equal to 1

B- the domain of function A is the set of real numbers is greater than 0  

The domain of the function B is the set of real numbers greater than or equal to 1

Step-by-step explanation:

The function A is

By definition we know that the function is not defined for values of

Therefore the domain of is:

All real numbers greater than 0.

Function B shown in the graph is a curve that goes in x from x = 1 to infinity.

Therefore it can be seen that the domain of this function is:

all real numbers greater than or equal to 1.

.

Therefore the correct option is B.

Choice B is correct; the domain of function A is the set of real numbers greater than 0  

The domain of the function B is the set of real numbers greater than or equal to 1

Step-by-step explanation:

The domain of a function refers to the set of x-values for which the function is real and defined. The graph of function B reveals that the function is defined when x is equal 1 and beyond; that is its domain is the set of real numbers greater than or equal to 1 written in interval notation as;

On the other hand, the natural logarithm function is defined everywhere on the real line except when x =0; this will imply that its domain  is the set of real numbers greater than 0 . In fact, the y-axis or the line x =0 is a vertical asymptote of the natural log function; meaning that its graph approaches this line indefinitely but neither touches nor crosses it.

the answer to your question a or b but i am pretty sure it is b. i hope this : )

d

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
