Give the domain and range. A: Domain: {-2,0,2} range {4,6,8}
B: Domain: {0,2} range {6,8}
C: Domain: {4,6,8} range {-2,0,2}
D: Domain: {6,8} range {0,2}

Option (a) is correct.

i.e. Domain: {-2,0,2} range {4,6,8}

Step-by-step explanation:

From the given diagram

The set X = {-2, 0, 2}

The set Y = {4, 6, 8}

We know that the domain of a relation is the set of all the x-values of the set X.

Thus, the domain: {-2, 0, 2}

We know that the range of a relation is the set of all the y-values of the set Y.

Thus, the range: {4, 6, 8}

Hence, option (a) is correct.

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
