Q. The parabola y=x2 is shifted down by 3 units and to the left by 2 units.What is the equation of the new parabola?y=
Shift down by 3 units: To shift the parabola y=x2 down by 3 units, we subtract 3 from the y-value. This gives us the equation y=x2−3.
Shift left by 2 units: To shift the parabola to the left by 2 units, we replace x with (x+2) in the equation. This gives us the equation y=(x+2)2−3.
Expand and simplify: Now we expand the equation y=(x+2)2−3 to check for any simplification. Expanding (x+2)2 gives x2+4x+4. So the equation becomes y=x2+4x+4−3.
Final equation: Simplify the equation by combining like terms. The constant terms 4 and −3 combine to give 1. So the final equation of the new parabola is y=x2+4x+1.
