Find the domain and range of the exponential function h(x) = 125x.
kirill [66]
H(x) = 125^x

Domain: all the real numbers (from negative infinity to infinity)

Range: all the positive real numbers.

As x decreases 125^x decreases approaching to 0. The function will never reach the value 0 but will approximate to it as x goes to negative infinity. The rate of decreasing gets lower and lower, with a limit of zero, when x becomes more and more negative.

As x increases 125^x increases indefinetely and at an increasing rate. That means that the increase is accelerated (the bigger the value of x the bigger the rate of increasing).

A box contains four equal sized cards labeled 1,3,5,7 Tim will select one card from the box What is the probability that Tim wil
Mice21 [21]

Answer:

0 is the probability that Tim will select a card labeled with a number 6.

Step-by-step explanation:

We are given the following in the question:

Number of cards = 4

Cards with labels:

1,3,5,7

Tim will select one card from the box. We have to find the probability that Tim will select a card labeled with a number 6.

Formula:

\text{Probability} = \displaystyle\frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}

\text{P(Label 6) = }\dfrac{0}{4}= 0

0 is the probability that Tim will select a card labeled with a number 6. Thus, it is an impossible event.
