What is the domain of the function below? {(0,2), (3,1), (5,2), (8,4)}? (1point)
Is the following relation a function? {(0.3, 0.6), (0.4, 0.8), (0.3,0.7), (0.5,0.5)} (1point)
the domain is the set of x-coordinates: {0,3,5,8}
If any x maps to more than one y, it's not a function. So, what do you think?
Who has all the answers
kk, thx Steve :)
the domain is the set of x-coordinates: {0,3,5,8}
To find the domain of a function, you need to determine all the possible input values, or independent variables, that the function can take.
In the given function, the input values are 0, 3, 5, and 8. Therefore, the domain of the function is {0, 3, 5, 8}.
Now, let's move on to the second question about whether the given relation is a function.
To determine if a relation is a function, you need to check if each input value has a unique output value. In other words, for each input value, there can only be one corresponding output value.
In the given relation, the input value 0.3 has two corresponding output values, 0.6 and 0.7. Since there is more than one output value for a single input value, this relation is not a function.
