If the zeros of a quadratic function , f, are -3 and 5, what is the x-coordinate of the vertex of the function f?

we know function "f" has zeros at -3 and 5, namely x = -3 and x = 5, well for a quadratic, the vertex is half-way between those two zeros,

-3................... 1....................5

so the x-coordinate is at 1.  Check the picture below, regardless of the shape of the parabola.

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
