Answer:

y = (x-5)² - 3

Explanation:

Given:


\displaystyle \large{f(x)=(x-1)^2+2}

  • translates 4 units right
  • 5 units down

Transformation:


\displaystyle \large{f(x-a)} is translation of a units to the right


\displaystyle \large{f(x)-b} is translation of b units down.

Therefore:


\displaystyle \large{g(x)=f(x-4)-5} is our new equation or transformation:


\displaystyle \large{g(x)=[(x-4)-1]^2+2-5}\\\displaystyle \large{g(x) = [x-4-1]^2-3}\\\displaystyle \large{g(x)=(x-5)^2-3}

Therefore, the new equation is y = (x-5)² - 3
