Converting from vertex to standard form y = (x + 1) {}^(2) - 3 y = (x - 2) {}^(2) + 3 ​

Question

Converting from vertex to standard form


`y = (x + 1) {}^(2) - 3`

`y = (x - 2) {}^(2) + 3`
​

Answer 1

Explanation:

y = (x+1)² - 3

 = (x²+2x+1)-3

 = x²+2x-2

:::::

y = (x-2)² + 3

 = (x²-4x+4) + 3

 = x²-4x+7
