Answer 1

Which are true of the function f(x) = 49()x? Check all that apply.

The domain is the set of all real numbers.  

The range is the set of all real numbers.  

The domain is x > 0.

The range is y > 0.

As x increases by 1, each y-value is one-seventh of the previous y-value.

The initial value for the function is 7.

The correct answer choices are:

The domain is the set of all real numbers.  

The range is y > 0.

As x increases by 1, each y-value is one-seventh of the previous y-value.

Answer 2

Answer:

• the domain is the set of all real numbers.
• the range is the set of all real numbers.

Explanation:

In an equation with two variables, there is one independent variable and one dependent variable. The set of all values for independent is known as domain. The set of all corresponding values of dependent variable is known as range.

In the given equation:

f(x) = 49 (x)

x is an independent variable and f(x) is a dependent variable.

Since no condition is mentioned for x, the variable x can take any possible real numbers. Thus, domain is a set of all real numbers.

And corresponding to value of x, f(x) can also have any possible real number. Thus, the range is also a set of all real numbers.
