The graph of a polynomial changes direction twice and has only one root What can you say about the polynomial?

It is a polynomial of odd power - probably a cubic. It has only one real root and its other two roots are complex conjugates.
It could be a polynomial of order 5, with two points of inflexion, or two pairs of complex conjugate roots. Or of order 7, etc.

What is ac and what is DC?
DC stands for "direct current", AC for "alternating current". A direct current flows in a single direction; an alternating current changes its direction all the time, typicall 100 or 120 times a second (twice the frequency, which is measured in hertz).

Why is it harder to notice seasonal changes near the equator?
Because they get midsummer twice a year and midwinter twice a year. The sun is never very far from being overhead at noon even in winter.
What is the greatest number of real roots a polynomial of degree 2 can have?
A real root is when a quadratic equation, or the graph of a polynomial, crosses the x axis, or when the y coordinate is equal to 0. On any polynomial to the degree of two, when graphed the line follows a smooth arc in the shape of a "U" or and upside down "U". Since there are only two prongs to the parabola, or arc, it can only cross the x axis twice, if at all. So there can only be 2 real roots.
Electrically how is AC different from DC current?
DC is direct current, current travels in one direction. AC is alternating current, current changes direction twice per cycle. 60 Hertz would change direction 120 times per second.
What happens when light passes from three different mediums like water to glass and glass to air?
In that case, it will change direction twice - in this example, once when it changes over from water to glass, and once when it changes from glass to air.
Which type of line that tests for a function?
Vertical line. If you can draw a vertical line through some part of a graph and it will intersect with the graph twice, the graph isn't a function.

What does it mean when the graph of a quadratic function crosses the x axis twice?
When the graph of a quadratic crosses the x-axis twice it means that the quadratic has two real roots. If the graph touches the x-axis at one point the quadratic has 1 repeated root. If the graph does not touch nor cross the x-axis, then the quadratic has no real roots, but it does have 2 complex roots.
What refracts light twice in the same direction?

How can i draw a line graph to represent a car traveling at twice a speed?
i dont think you can use a line graph for that. i think a table would be better...
