I’m positive it’s Option 4
Answer:
yes, the given relation is a function.
Step-by-step explanation:
The given relation is
{(–3, –2), (–1, 0), (1, 0), (5, –2)}
A relation is called function if each element of the domain is paired with exactly one element of the range.
It means for each value of x there exist a unique value of y.
In the given relation for each value of x there exist a unique value of y.
Therefore the required solution is yes and this relation is a function.
Answer:
C. 10 times greater
Step-by-step explanation:
every time you move left a number space, the value increases by a multiple of 10x (the opposite is true for moving right)
for example:
1.0
10.0
100.0
<u>1</u><u>0</u><u> </u><u>is </u><u>1</u><u>0</u><u>x</u><u> </u><u>greater </u><u>than </u><u>1</u>
<u>1</u><u>0</u><u>0</u><u> </u><u>is </u><u>1</u><u>0</u><u>x</u><u> </u><u>greater </u><u>than </u><u>1</u><u>0</u><u> </u><u>or </u><u>1</u><u>0</u><u>0</u><u>x</u><u> </u><u>greater </u><u>than </u><u>1</u>
<u>*</u><u>notice </u><u>how </u><u>the </u><u>number </u><u>1</u><u> </u><u>is </u><u>moving </u><u>one </u><u>space </u><u>to </u><u>the </u><u>left</u>
Step-by-step explanation:
By Descrates' Rule of Signs,
x² + 99x + 127 changes sign 0 times.
Hence it has 0 positive roots.
Since the discriminant b² - 4ac is also positive, there are 2 real distinct roots.
Hence both the roots are negative. (B)
