What is the derivative of x3-8?
Let y = x3 - 8, then y' = 3x2 + 0 = 3x2.
What is the value of x in this equation y equals 3x2?
x = +/- sqrt(y/3)
Is y equals 3x squared plus 1 a linear equation?
No. Y=3X2+1 is a Binomial Equation.
Does y equals 3x2 plus 2x-3 represent a function?
Yes.
What is the Factor 3x2 plus 6xy plus 3y2?
(3x + 3y)(x + y) or 3(x + y)2
3x2 - y 6?
3x2-y=6 3x2-y=6
What is the derivative of x3-8?
Let y = x3 - 8, then y' = 3x2 + 0 = 3x2.
When you completely factor 3x2 y what do you get?
3 * x * x * y
What is the value of x in this equation y equals 3x2?

What is the x-coordinate of the of the vertex of y equals -3x2 plus 12x-5?
You can find the x-coordinate of it's vertex by taking it's derivative and solving for zero: y = -3x2 + 12x - 5 y' = -6x + 12 0 = -6x + 12 6x = 12 x = 2 Now that we have it's x coordinate, we can plug it back into the original equation to find it's y coordinate: y = -3x2 + 12x - 5 y = -3(2)2 + 12(2) + 5 y = -12 + 24 + 5 y = 17 So the vertex of the parabola y = -3x2 + 12x - 5 occurs at the point (2, 17).
Is y equals 3x squared plus 1 a linear equation?
No. Y=3X2+1 is a Binomial Equation.
Does y equals 3x2 plus 2x-3 represent a function?
Yes.
What is the Factor 3x2 plus 6xy plus 3y2?
(3x + 3y)(x + y) or 3(x + y)2
How does the graph of y equals 3x2-5 compare with the graph of y equals 3x2 plus 8?
The figures are exactly the same, but every point on the first graph is exactly 13 below the corresponding point on the second one.
Factor x2y-3x2-2y plus 6?
(x2 - 2)(y - 3)
