The a value of a function in the form f(x) = ax? + bx + c is negative. Which statement must be true?
The vertex is a maximum
The y-intercept is negative
The x-intercepts are negative
The axis of symmetry is to the left of zero

Areflection of shape i across the y-axis, followed by a , and then a translation left 6 units and down 4 units confirms congruence between shape i and shape ii. alternatively, a of shape ii about the origin, followed by a reflection across the y-axis, and then a translation right 4 units and up 6 units confirms congruence between shape ii and shape i.
