Graphs

What really is a graph?
What is a graph used for?
What are the key things to look for in a graph?
What are some other ways of saying x-intercept?
Can you determine or have an idea of how many x-intercepts may be present?

  2. oyher ways in saying x-intercepts are roots and factors.

  3. yes you can determine how many x-intercepts are present by looking at the highest power of the x variable in the expression or equation. For example in the equation 7x^2 + 2x + 5, since the highest power of the x variable is 2 the graph will cut the x intercepts at 2 points.

  5. a graph is a comparison between two thing which a related to each other, they have something in common.
    the y axis is the varible that is changing and the x axis is the variable you are manipulating
    example
    a distance vs time graph u use it to find speed
    the time is constant the distance will change it exist in period in this eg in one period of time 2m will be cover while in an other period 3m will be cover the speed determine it
    change in distance/ change in time
    also call the gradient of the above graph

  6. A graph is a diagram showing the relationship between to things that are related to each other.It can be represented by a curve or a straight line.

  7. key things to look for in a graph are:-
    .if it is increasing or decreasing
    .the shape of the graph (straight line/ curve)
    .the start and end point
    .where it cuts the x intercept.

    some other ways to say x intercept are factor or roots.

  12. a graph gives every point its own gradient

  16. i agree with misty.
    a graph can also show a starting point, which is the y intercept.

  17. the key things ilook 4 in a graph are the scales on both axis
    the labelling on both axis and the points plotted

    a graph is used to represnt information in an acurate form.

    key things to look out for in a graph are scale, y-axis, x-axis, title of graph

    another way of stating x-intercept is when the line cuts the x-axis at a certain point.

    there can only be 1 x-intercept present

  111. yes you can determine how many x-intercepts are present. times the graph of a quadratic function intersects the x-axis. The graph of a
    quadratic function can cross the x-axis at two points, one point, or no points at all. Without graphing a function, you can use factoring or the quadratic formula to determine the number of x-intercepts of that function.
    The maximum number of x-intercepts equals the degree of a polynomial.

    ReplyDelete
  120. A graph consists of two axes called the x (horizontal) and y (vertical) axes. These axes correspond to the variables we are relating

    ReplyDelete
  121. The point where the two axes intersect is called the origin. The origin is also identified as the point (0, 0).

  129. Key Things
    Key things to look for in a graph is their relationship and what kind e.g. Proportional relationship/linear (A straight line is observed and passes through the origin/some other pt.)Also is their a maximum/minimum value/point.

    Note: It depends on the type of graph that determines what to look for.eg. Quadratic graph- look for where graph crosses x/y axis

    ReplyDelete

  164. the key things are
    - the roots, or where the graph cuts the x axis.
    -if it is increasing or decreasing
    -if a curve, if its a maximum or minimum
    -the title ofcourse, you must know what the graph is about

    ReplyDelete
  165. x- intercept.
    where the line or curve cuts the x-axis.
    or the roots of the equation whether it be a curve or a straight line.

    ReplyDelete
  166. in a straight line graph, there can only be one x- intercept.
    and by some eqn, you can find the roots and determine whether they would be real or not.
    b^2=4ac....i cant really member..but that sounds familiar.
