range of absolute value of x-10

Since this is an absolute value it can never be less than 0. The range is 

h(x)= abs(-2x) What are the domain and range? x=-3 What are the domain and range?

h(x) has domain (-oo,oo) and range [0,oo) 
x=-3 hs domain {-3} and range (-oo,oo)

Find the range of the function f(x)= 8^x - 24 a. -infinity, -24, b. -24, infinity, c. -infinity, infinity, d. -24, 0

b) because the exponential function decays to 0 but grows indefinitely

find the domain and range of y=3/(2x-3)

and range     

Give the domain and range of G. Write your answers using set notation

Suppose that the relation is defined as follows. {(5,5),(8,0),(6,-2),(-9,-8)} Give the domain and range of G. Write your answers using set notation

G={(5,5),(8,0),(6,-2),(-9,-8)}
The domain is the set of x-coordinates and the range is the set of y-coordinates:

dom(G)={5,8,6,-9}
ran(G)={5,0,-2,-8}

:)

Find the domain and range.

Find the domain and range.
R={( -4, -7), ( 12, 5), ( 11, -9), ( 11, -3)}


Solution:

The domain of a relation is the set of all first coordinates so we can write Dom R={-4, 12, 11}

The range of a relation is the set of all second coordinates so we can write Ran R={-7, 5, -9, -3}
