Can someone help me find the x-intercepts of f(x) = 3x^2 + 6x - 24?

Which set of reflections would carry trapezoid abcd onto itself? a) x-axis, y=x, y-axis, x-axis b) x-axis, y-axis, x-axis c) y=x, x-axis, x-axis d) y-axis, x-axis, y-axis, x-axis

Can someone check if i did this right since i really want to make sure it’s correct. if you do you so much
