The a value of a function in the form f(x) = ax2 + 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.

A) the vertex is a maximum.

Step-by-step explanation:

The function f(x) = ax^2 + bx + c, where is "a" is negative.

a < 0, means the graph of the parabola opens down. when the parabola opens down we will have the vertex as a maximum point.

Therefore, answer is A) the vertex is a maximum.

Hope this will helpful.

Thank you.
