A. vertex (-1, 4); axis is x = -1;
x-intercepts are 1 and - 3; y-intercept is 3
B. vertex (1, 4); axis is x = 1;
x-intercepts are -1 and 3; y-intercept is 3
C. vertex (1, -4); axis is x = 1;
x-intercepts are -1 and 3; y-intercept is -3
D. vertex (-1, -4); axis is x = -1;
x-intercepts are 1 and - 3; y-intercept is -3
