The function graphed is reflected across the x-axis to create a new function. which is true about the domain and range of each function? both the domain and range change. both the range and domain stay the same. the domain stays the same, but the range changes. the range stays the same, but the domain changes.

the correct answer is:

the domain stays the same, but the range changes.

explanation:

by reflecting a function across the x-axis, the y-values change.   this is because a reflection through the x-axis negates the y-values, making them the opposite of what they were.

the x-values, however, stay the same.   this means the domain, the x, stays the same, while the range, the y, changes.

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

answer: sorry i can't you.
