What is the domain and range of f(x)=(1/5)^x

Answersadfs:

Domain of the exponential function is (-∞, ∞)

the range is (0, ∞)

Stasdfep-by-step explanation:

Domain is the set of x values for which the function is defined. there is no restriction for x in exponential function.

Domain of the exponential function is (-∞, ∞)

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

For range, of we plug in positive or negative number for x  the value of y is always positive because we have exponent x

Hence the range is (0, ∞)

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
