What is the domain of y equals x2?
The domain of y = x2 is [0,+infinity]
If y equals -2 when x equals 4 find x when y equals 5?
x1:y1 = x2:y2 4:-2 = x2:5 x2 = (4*5)/-2 x2 = -10
What is the effect on the graph of the equation y equals x2 plus 2 when it is changed to y equals x2 - 4?
the graph is moved down 6 units
What is the curvature of y equals x squared?
Y = X2 forms a parabola
What does the equation y equals x2 - 6x plus 2 become after completing the square?
y = x2 - 6x + 2 y = x2 - 6x + 9 - 7 y = (x - 3)2 - 7
What is the domain of y equals x2?
The domain of y = x2 is [0,+infinity]
Is y equals x2 a nonlinear equation?
If you mean y = x2, then yes, it is nonlinear.
If y equals -2 when x equals 4 find x when y equals 5?
x1:y1 = x2:y2 4:-2 = x2:5 x2 = (4*5)/-2 x2 = -10
What describes the translation of the graph of y equals x2 to obtain the graph of y equals -x2 - 3?
No translation will invert a quadratic graph.
What is the effect on the graph of the equation y equals x2 plus 2 when it is changed to y equals x2 - 4?
the graph is moved down 6 units
Y equals -x2 plus 4x-3?
y = 4x-3
What is the curvature of y equals x squared?
Y = X2 forms a parabola
Is y equals x2 plus 1 a function?
Yes. Think of y as being a function of x. y = f(x) = x2 + 1
Y equals x2 plus 4 lies on which axis?
y = x2 + 4 The graph is a parabola, with its nose at y=4 on the y-axis, and opening upward.
What does the equation y equals x2 - 6x plus 2 become after completing the square?
y = x2 - 6x + 2 y = x2 - 6x + 9 - 7 y = (x - 3)2 - 7
If x equals 6 and y equals 2 then x² divided by y equals what?
x2 / y = (6)2 /2 = 36/2 = 18
What is the point of intersection of the parabolas y equals x2 plus 20x plus 100 and y equals x2 -20x plus 100 showing work?
If: y = x2+20x+100 and x2-20x+100 Then: x2+20x+100 = x2-20x+100 So: 40x = 0 => x = 0 When x = 0 then y = 100 Therefore point of intersection: (0, 100)
