What are the domain and range of an exponential parent function? Help please

Mathematics

a_sh-v [17]1 year ago

The domain and the range of an <em>exponential parent</em> function, that is, y = eˣ are equal to all <em>real</em> numbers and <em>non-negative</em> numbers, respectively. (Correct choice: C)

<h3>How to determine the domain and range of an exponential function</h3>

In this problem we should determine what an <em>exponential parent</em> function is. The most common <em>exponential</em> functions have the following form:

y = A\cdot e^{B\cdot x} + C     (1)

(1) is an <em>exponential parent</em> function for A = 1, B = 1 and C = 0.

All functions are relations with a domain and range, the domain is an <em>input</em> set related to the range, that is, an <em>output</em> set. In the case of an <em>exponential parent</em> function, the domain and the range of the expression are \mathbb{R} and y ≥ 0, respectively. (Correct choice: C)

irakobra [83]

Answer:

1 / 5040

Step-by-step explanation:

The number of ways that 7 basketball players can be arranged is 7! = 5040.  Only one of these arrangements is alphabetical.  So the probability is 1/5040.

Find the measure of angle x in the figure below: A.) 35° B.) 48° C.) 69° D.) 78°
prisoha [69]

Answer:

x = 48

Step-by-step explanation:

First find y

52+y+59 = 180 since they from a straight line

y = 180-59-52

y = 69

Then we know the angles of a triangle add to 180

x+y+63 = 180

x+69+63 = 180

x = 180-69-63

x =48

Misha Larkins [42]

Answer:

a) P(X

And we can find this probability using the normal standard table:

P(z

b) P(X>48)=P(\frac{X-\mu}{\sigma}>\frac{48-\mu}{\sigma})=P(Z>\frac{48-46.8}{1.75})=P(Z>0.686)=1-P(z

And we can find this probability using the normal standard table and the complement ruel:

P(Z>0.686)=1-P(z

c) P(46.8-1.5*1.75

And we can find this probability with this difference:

P(-1.009

And in order to find these probabilities we can use the tables for the normal standard distribution, excel or a calculator.  

P(-1.009

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".  

Assuming the following questions:

Part a: What is the probability that the maximum speed is at most 50 km/h?

Let X the random variable that represent the heights of a population, and for this case we know the distribution for X is given by:

X \sim N(46.8,1.75)  

Where \mu=46.8 and \sigma=1.75

We are interested on this probability

P(X

And the best way to solve this problem is using the normal standard distribution and the z score given by:

z=\frac{x-\mu}{\sigma}

If we apply this formula to our probability we got this:

P(X

And we can find this probability using the normal standard table:

P(z

Part b: What is the probability that maximum speed is at least 48 km/h?

P(X>48)=P(\frac{X-\mu}{\sigma}>\frac{48-\mu}{\sigma})=P(Z>\frac{48-46.8}{1.75})=P(Z>0.686)=1-P(z

And we can find this probability using the normal standard table and the complement ruel:

P(Z>0.686)=1-P(z

Part c:What is the probability that maximum speed differs from the mean value by at most 1.5 standard deviations?

P(46.8-1.5*1.75

And we can find this probability with this difference:

P(-1.009

And in order to find these probabilities we can use the tables for the normal standard distribution, excel or a calculator.  

P(-1.009
