Question

Which is the range of the function f(x) =One-seventh(9)x?

Answer 1

Answer:

all real numbers greater than 0

Step-by-step explanation:

Range is the set of y values for which the function is defined

using a graphing tool

The domain is the interval ----> (-∞,∞) All real numbers

For all positive and negative values for x the value of y is always positive

The range is the interval ---->(0,∞)

All real numbers greater than 0

Answer 2

Answer:

all real numbers greater than 0

Step-by-step explanation:

we have

$f(x)= \frac{1}{7} (9)^x$

we know that

Range is the set of y values for which the function is defined

using a graphing tool

see the attached figure

The domain is the interval ----> (-∞,∞) All real numbers

For all positive and negative values for x the value of y is always positive

The range is the interval ---->(0,∞)

$y> 0$

All real numbers greater than 0
