Answer:
desculpa mas eu não sei a resposta mais eu vou ver se posso te ajudar taaa
The vertex of the function f(x) = |x - a| is in (a, 0).
f(x) + a - shift the graph of function f(x) a units up.
Therefore:
The verex of y = |x + 5| is in (-5, 0).
The vertex of y + 7 = f(x) = |x + 5| + 7 is in (-5, 0 + 7) = (-5, 7).
S = 7x^2....divide both sides by 7
1/7s (same as s/7) = x^2...now take sqrt of both sides
(+ - ) sqrt 1/7s = x
It’s C because it works and it should help you get it right
