Transform y=-x²: Shifting 6 Units Left and 1 Unit Down

Question

Which equation represents the following function shifting 6 spaces to the left and one space down?

y=x2 y=-x^2

Video Solution

Step-by-Step Solution

To solve this problem, we will apply transformations to the original function:

  • Step 1: Horizontal Shift
  • The function y=x2 y = -x^2 needs to be shifted 6 units to the left. In terms of algebraic manipulation, this means taking x x in the function and replacing it with (x+6) (x + 6) . The equation becomes:

    y=(x+6)2 y = -(x + 6)^2

  • Step 2: Vertical Shift
  • Next, we shift the function 1 unit down. This involves subtracting 1 from the entire expression we obtained from the horizontal shift:

    y=(x+6)21 y = -(x + 6)^2 - 1

This captures both the horizontal and vertical shifts. Therefore, the resulting function after applying these transformations is:

y=(x+6)21 y = -(x + 6)^2 - 1

Answer

y=(x+6)21 y=-(x+6)^2-1
