Answer:  y = -(x + 2)²

<u>Step-by-step explanation:</u>

The vertex form of a quadratic equation is: y = a(bx - h)² + k    where

  • a: vertical stretch (if negative it is a reflection across x-axis)
  • b: horizontal stretch (if negative it is a reflection across y-axis)
  • h: horizontal shift (negative is left and positive is right)
  • k: vertical shift (negative is down and positive is up)
  • (h, k): vertex of the function

Given: reflection over x-axis → a = -1,   two units left → c = -2

Input those values into the equation:  y = -(x - (-2))²

                                              simplify:   y = -(x + 2)²

The landscape artist who designed New York City’s
timama [110]

The landscape artist who designed New York City’s Central Park believed that providing scenic settings accessible to all would not only benefit the public’s physical and mental health <u>and also foster a sense of democracy. </u> (Option D: but also foster a sense of democracy).

<h3>What is sentence correction?</h3>

Sentence correction or sentence improvement is a type of grammatical practice where a sentence is given with a word or a phrase that requires grammatical changes or improvement.

Now,

  • When 'not only' is used, 'but also' must come after it. When utilizing a correlative conjunction like "not only," "but also," the goal should be parallelism, meaning that the words that come after both sides of the conjunction should be from the same part of speech.
  • Here, using 'and' after 'not only...' distorts the structure of the sentence.

Hence, Option D is the right response, i.e., The landscape artist who designed New York City’s Central Park believed that providing scenic settings accessible to all would not only benefit the public’s physical and mental health <u>and also foster a sense of democracy. </u> (Option D: but also foster a sense of democracy).
