Question

Which of the following could be the equation of F(x)?

Answer 1

Answer is A because it’s moved 2 to the right which makes it x-2 and it’s moved 1 down so -1 and it needs to be -x because it’s facing down so the answer is A

Answer 2

Option A. f(x) = -(x - 1)² - 1

Explanation:

After the transformation of g(x) = x², vertex of the red parabola f(x) is (2, -1).

Therefore, equation of the parabola in the vertex form will be

f(x) = (x - 2)² - 1

Since opening of the parabola is downwards so the function will be

f(x) = - (x - 2)² - 1

This function matches with option A.
