Which statement describes the translation of y = −1 over 5(x + 5)2 + 2 from standard position?
1 answer:
Answer:
Option B
Step-by-step explanation:
Given equation is
The original graph would be
From this transformations done are
a) horizontal shift of 5 units to the left
b) shrink vertical by scale factor 1/5
c) vertical shift of 2 units up
Hence option A is not right
Option B is right.
Similarly C and D are not right.

Answer: B)
<h2>Hello!</h2>
The answer is:
The interval notation will be: (-∞,-1.59) and (-4.41,∞+)
<h2>Why?</h2>To solve the expression, we need to perform the following steps:
- Find the roots or zeroes of the expression:
Using the quadratic equation, we have:
We are given the quadratic expression:
Where,
Then, substituting and calculating we have:
- Inequality interpretation:
Now that we already know the roots of the quadratic expression, and we can see that the parabola open upwards (positive quadratic coefficient), we can conclude that the function is less than 0 between the numbers -4.41. and -1.59
The interval notation will be:and (-∞,-1.59) and (-4.41,∞+)
Have a nice day!
