What is the domain of the relation shown below?
{(4,2),(1,1),(0,0),(1,-1),(4,-2)} 1) {0,1,4}
3) (-2,-1,0, 1, 2,4}
2) (-2,-1,0, 1, 2}
4) (-2,-1,0,0,1, 1, 1, 2,4,4}
Enter your answer

1) {0,1,4}

Step-by-step explanation:

(x,y)

domain is x

range is y

so in this case the domain is 0,1,4    

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
