i am 12 and the answer is:
The vertex is: -5/8, 7/8
X intercepts are: -3/8 AND -12 7/8

I believe the following answers will be found correct:
y = 8x2 + 10x + 3 = (4x + 3)(2x + 1).
The x-intercepts occur at x = -¾ and x = -½.
The vertex occurs at x = -5/8, y = (-5/2 + 3)(-5/4 + 1) = (1/2)(-1/4) = -1/8;
that is, at (-5/8, -1/8).
The parabola is, of course, concave-upwards.

How do you determine if the graph of a quadratic function has a min or max from its equation?
If x2 is negative it will have a maximum value If x2 is positive it will have a minimum value
What is the name of the graph of a quadratic function?
The parabola
How are the real solutions of a quadratic equation related to the graph of the quadratic function?
The real solutions are the points at which the graph of the function crosses the x-axis. If the graph never crosses the x-axis, then the solutions are imaginary.
Is a graph of a quadratic function always a parabola?
No. It can also be a circle, ellipse or hyperbola.
The line that cuts the graph of a quadratic function in half is called the axis of what?
It is the axis of symmetry.
What do you call the graph of a quadratic function?
the graph of a quadratic function is a parabola. hope this helps xP
How can you use a graph to find zeros of a quadratic function?
The zeros of a quadratic function, if they exist, are the values of the variable at which the graph crosses the horizontal axis.
