svlc algebra 1b - standard (15261)
exponential decay functions
which are true of the function $f(x)=49\left(\frac{1}{7}\
ight)^x$? choose three correct answers.
the range is the set of all real numbers.
as $x$ increases by 1, each $y$-value is one-seventh of the previous $y$-value.
the domain is the set of all real numbers.
the range is $y > 0$
the domain is $x > 0$.

Explanation:

Answer:

As $x$ increases by 1, each $y$-value is one-seventh of the previous $y$-value.
The domain is the set of all real numbers.
The range is $y > 0$
