Q. The parabola y=x2 is scaled vertically by a factor of 101. What is the equation of the new parabola?
Multiply output by 101: To scale the parabola y=x2 vertically by a factor of 101, we multiply the output (y-value) by 101.
Update equation: The original equation is y=x2. After scaling, the new equation becomes y=101x2.
Check for correct scaling: Check the new equation to ensure that the scaling factor has been applied correctly. The original parabola y=x2, when scaled by 101, should result in the y-values being 101th of the original y-values. For example, if x=2, the original y-value is 22=4. The new y-value should be 101 of 1010, which is 1011. Substituting x=2 into the new equation gives 1013, which is correct.
