A. Blue: y = -3x + 8
Black: y = 3x + 2
B. You find the ordered pair (x, y) that is a solution for both functions ( find the point where the two lines cross)
C. There’s two ways you can solve algebraically (using the equations); substitution and elimination. I don’t know which you need to use to answer but feel free to use my notes on how to do substitution for help. I don’t really have any on elimination ( it’s so easy you don’t even really need notes) or I would use them to explain.

Question 2
fomenos

Answer:

D. (-2,-5), (0, -7), (1, -4)

Step-by-step explanation:

From Function Theory we must remember that range of a function is the set of images related to elements of the domain. In this case, we must find the image of each of the three elements that forms the domain of f(x, y) = (y+2, -x-4), which are: A(x,y) = (1, -4), B(x,y) = (3,-2) and C(x,y) = (0,-1).

Then we proceed to find all elements of range:

A(x,y) = (1, -4)

f(1,-4) = (-4+2,-1-4)

f(1,-4) = (-2,-5)

B(x,y) = (3,-2)

f(3,-2) = (-2+2,-3-4)

f(3,-2) = (0,-7)

C(x,y) = (0,-1)

f(0,-1) = (-1+2,0-4)

f(0,-1) = (1,-4)

Which corresponds to option D.
