Answer:
b; vertically compressed by a factor of 2
Step-by-step explanation:
Here, we want to select from the options, the transformation that was not done on the parent function;
a) shifted up seven units
This was done
as we can see, we have + 7 from the initial 0 point
b) vertically compressed by a factor of 2
This is wrong
What we had is 1/2 multiplied by x
If there is any compressor done, it is to a factor of 1/2 and not 2
This, is thus our answer
Answer:
Option A. x < -4
Step-by-step explanation:
The given function is f(x) = -(x + 6)(x + 2)
General form of the function will be,
f(x) = -(x² + 2x + 6x + 12)
= -(x² + 8x + 12)
Vertex form of the function will be,
f(x) = -[x² + 2(4)x + 12]
= -[(x² + 2(4)x + 16) - 16 + 12]
= -(x + 4)² + 4
Therefore, parabola for the function above will open down with vertex (-4, 4) as shown in the graph attached.
Graph shows the function is increasing in x < -4 and decreasing in x > -4.
Therefore, Option A. is the correct answer.

Answer:
<em><u>38 15/16</u></em>
Step-by-step explanation:
39 + 1/8n
Since the n = -1/2, replace the 'n' in the original equation with that number
39 + 1/8 (-1/2)
Multiply numerator-to-numerator and denominator-to-denominator
1/8 times -1/2 equals -1/16
(Because a positive times a negative equals a negative)
Now your complete equation is:
39 + -1/16
Add those numbers together to get <u>38 15/16</u>
