Evaluate the function f(x)=10-x for the domain {-2, 0, 2}

For this case we have a function of the form , where:

We must find the value of the function when:

Thus, we have that the function has a value of when

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
