Step-by-step explanation:
√121 - √-192 - √4 + √-48
= 11 - 192i - 2 + 48i
= 9 - 144i
= 9(1 - 16i).
It’s the point where the parabola crosses its axis of symmetry
Since your slope is 3, (the number for slope is always right before x) and your y-intercept is one (that is always the number after the x) your answer would be B
