### 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.

### How is the function differentiable in graph?

If the graph of the function is a continuous line then the
function is differentiable.
Also if the graph suddenly make a deviation at any point then
the function is not differentiable at that point .
The slope of a tangent at any point of the graph gives the
derivative of the function at that point.

### How can you tell the difference graph or function?

A function describes the relationship between two or more
variables. A graph is a kind of visual representation of one or
more function. A line or curve seen on a graph is called the graph
of a function.

For any point in the domain, a function can map to only ine
point in the range or codomain. In simpler terms, it means that
(for a two dimensional graph), a vertical line can intersect the
graph of the function in at most one point.

###### Asked in Algebra

### Which statement is a correct interpretation of the vertical line test?

A-If there exists a vertical line that intersects the graph at
exactly one point, the graph represents a function.
B-If there exists a vertical line that intersects
the graph at exactly one point, the graph does not represent a
function.
C-If there exists a vertical line that intersects the graph at
more than one point, the graph represents a function.
-DIf there exists a vertical line that intersects the graph at
more than one point, the graph does not represent a function

### What is the range of quadratic function?

The range of a function when you consider a graph is how high
and how low it goes. A quadratic function is usually an arch that
goes up to a high point and then back down like the arch of a
kicked ball.
Or, it can be the reverse which goes down and then up in a
mirror image of a kicked ball.
The range is what y values would be needed to show ALL the
graph.
Example;
y=x^2+5x-6
The graph crosses the x axis at -5 and 1 it goes down then back
up.
The range is from infinity down to -49/4

###### Asked in Algebra

### How do you graph the slope of a function?

For example, if the slope at a certain point is 1.5, you can
draw a line that goes through the specified point, with that slope.
The line would represent the slope at that point.
If you want to graph the slope at ALL POINTS, take the
derivative of the function, and graph the derivative. The
derivative shows the slope of a function at all points.
