Number 10 is C
The original equation was y = (x^2 + 1) + 3
We have to multiply it by -1 to reflect it across the x-axis and we must subtract 3 to bring it down 3
y = -(x^2 + 1)
Number 11 is A
The parabola is compressed and it has been translated up by 1, so we must multiply the original equation by some constant (in this case 2) and add 1
y = x^2 becomes y = 2x^2 + 1
