What does x2 that is greater than or equal to 9 look like on a graph?
It consists of two disjointed line segments: x ≤ -3 and x ≥ 3.
What is a function whose graph is not a straight line?
y = x2
Give you an example of a non linear equation?
y=x2; if you graph it, it is not a line.
What do you call the point where a line on a graph changes slope?
Nothing particular. The graph of y = x2, for example, changes slope at each point on the graph.
What does the graph look like for this equation y x2 10x 25?
if y = x2 + 10x + 25 then y = (x + 5)2 This tells us that the graph would be a parabola, with it's vertex at (-5, 0), and a range of 0 to infinity.

What kind of equation has a graph that is not a straight line?
y=x2
How you graph the slope on a graph?
you need 2 points on the line y2-y1 slope=----- x2-x1
How do you determine the slope of a line on an graph?
Rise divided by run. (Y2 - Y1) / (X2 - X1) - with (X1, Y1) and (X2, Y2) being two points on the graph.
Give you an example of a non linear equation?
y=x2; if you graph it, it is not a line.
How do you find the gradient of a line from a graph?
Select two points on the graph and suppose their coordinates are (x1, y1) and (x2, y2) then the gradient = (y1 - y2) / (x1 - x2) provided that x1 and x2 are different. If not, the gradient is not defined.

Nothing particular. The graph of y = x2, for example, changes slope at each point on the graph.
What does the graph look like for this equation y x2 10x 25?
if y = x2 + 10x + 25 then y = (x + 5)2 This tells us that the graph would be a parabola, with it's vertex at (-5, 0), and a range of 0 to infinity.
What does the Graph of x2 25 look like?
If f(x) = x2 + 25, then to plot f(x) on a graph would give you a parabolic curve extending infinitely upward with a minimum value of 25, and it's vertex at the point (0, 25).
How do you figure how the rate of change by looking at a graph?
formula to figure out the rate of change of a line on a graph m= y2-y1/x2-x1
What is the line of symmetry of the graph y equals -x2 plus 2x-2?
the line of symmetry would occur at x=0
