The Domain is the set of x coordinates in a relation; the independent variable

The Range is the set of y coordinates in a relation; the dependent variable

Function- a relation is a function of each number in the domain appears only once

*Its Only A Function If The Numbers In The Domain DO NOT Repeat*

What’s the domain and range for (2,4) (5,3) (-1,-4) (0,9) (-3,1)
Citrus2011 [14]

Step-by-step explanation: In this problem, we're asked to state the domain and range for the following relation.

First of all, a relation is just a set of ordered pairs like you see in this problem. The domain is the set of all x-coordinates for those ordered pairs. So in this case the domain or D is {2, 5, -1, 0, -3}.

The range is the set of all y-coordinates for those ordered pairs. So in this case our range or R is {4, 3, -4, 9, 1}.

Alexandra [31]

Answer:

h = -5*t +800

Step-by-step explanation:

The initial value is 800 ft

She is falling at a rate of 5 ft per second

That would be -5ft/s

We can write this in the form

y = mx+b

h = -5*t +800  where t is the number of seconds and h is the height above ground

Use the function below to find F(2)<br> F(x)=1/3•4^x<br> A.)2<br> B.)4<br> C.)8/3<br> D.)16/3
inna [77]

Answer:

D

Step-by-step explanation:

The function F(x) = \frac{1}{3}*4^x has value F(2) when x = 2 is substituted.

F(x) = \frac{1}{3}*4^x\\F(2) = \frac{1}{3}*4^2\\F(2) = \frac{1}{3}*16\\F(2) = \frac{16}{3}
