domain is correct for b and c
the graph is a function because each value of x has only one y value
hence answer is B
3 39/40 = 3.975
3 19/20 = 3.95
3 1/2 = 3.5
least to greatest : 3 1/2, 3 19/20, 3 39/40
To check if a relation is a function, given a mapping diagram of the relation, use the following criterion: If each input has only one line connected to it, then the outputs are a function of the inputs.
Answer:
tu debes de saber por qué si yo lo sé tú también no es verdad
Hey there. So first we need to know what the point slope form looks like.
It is Y-Y1=M (X-X1)
Knowing this you just plug in the given information.
M is equal to 1/6. So in this case all of the options have the correct m. Next we look at the Year value. We know Y is a positive 4. So the beginning of the equation is going to look like
Y+4=1/6 ( X-X1).
Nown plug in x. It would be a negative 5. Now your final answer would be option A. Hope the explanation helped.. :)
