Down
Step-by-step explanation:
The "parent function" is y = |x|, which opens up.
Changing the sign to y = -|x| flips (reflects) the graph over the x-axis, so the new graph opens down. Adding 9 shifts the graph up 9 units, but that does not change the way the graph opens.
See the attached image.
y = |x| purple
y = -|x| black
y = -|x| + 9 red

Step-by-step explanation:
<em>We must simplify each option to see if they are equivalent to .</em>
<em>Lets try A.</em>
can be simplified to
by dividing both the numerator and denominator by 3.
÷
A is correct!
<em>Lets try B</em>
simplifies to
. However, because this answer is not negative, it is not equivalent.
<em>Lets try C</em>
There is a negative in the numerator, making this fraction negative. So yes, .
- Bonus Info: If there was a negative in both the numerator and denominator, the two negatives would cancel eachother out, making the fraction positive
C is correct!
<em>Lastly, Lets try D</em>
There is a negative in the denominator, so this fraction is negative. can be simplified by dividing by 3 to
.
÷3 =
