How do you make a graph of a quadratic function that has x-intercepts at 0 and 4?
That's not enough information to draw the graph. All you know is that it crosses the x-axis at those 2 points. You don't know whether it opens upward or downward, or how far the nose is above or below the x-axis. You need more information about the function before you can graph it. This is just another way of saying that there are an infinite number of different quadratic functions that all have those same x-intercepts.
How can you tell whether a table of values represents a quadratic function?
Unless the operands form an arithmetic sequence, it is not at all simple. That means the difference between successive points must be the same. If that is the case and the SECOND difference in the results is constant then you have a quadratic.
Why is it better to have the quadratic function in vertex form instead of standard form?
If you want to graph the function, it is quite easy: y=a(x-h)2-k . . . you can plot the vertex (h,k); the 'a' tells you how wide or narrow the u-shape is, and whether it opens up or down.
What statement must be true of an equation before you can use the quadratic formula to find the solutions?
The quadratic formula can be used to find the solutions of a quadratic equation - not a linear or cubic, or non-polynomial equation. The quadratic formula will always provide the solutions to a quadratic equation - whether the solutions are rational, real or complex numbers.
Why is it necessary to periodically assess and evaluate policies?
is it necessary to have periodically assess and evaluate policies because it determines whether the policies are still current & relevant to your organisation & to its clients. Whether the policies suits their intended purpose or whether they need to be changed, eliminated, replaced or even updated.

What is the nature of zeros in quadratic function?
Nature Of The Zeros Of A Quadratic Function The quantity b2_4ac that appears under the radical sign in the quadratic formula is called the discriminant.It is also named because it discriminates between quadratic functions that have real zeros and those that do not have.Evaluating the discriminant will determine whether the quadratic function has real zeros or not. The zeros of the quadratic function f(x)=ax2+bx+c can be expressed in the form S1= -b+square root of D over 2a and S2= -b-square root of D over 2a, where D=b24ac.... hope it helps... :p sorry for the square root! i know it looks like a table or something...
How do numbers affect the trigonometric function?
Trigonometric functions are defined from a numeric domain to a numeric range. So the input number determines whether or not the function is defined for that value and, if so, what the value of the function is.
