- 5 = 3X = 2
add 2 to each side
- 3 = 3X
divide both sides integers by 3
- 1 = X
----------check in original equation
- 5 = 3(- 1) - 2
- 5 = - 3 - 2
- 5 = - 5

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.
What is the value of x in this equation y equals 3x2?
x = +/- sqrt(y/3)
Does y equals 3x2 plus 2x-3 represent a function?
Yes.
Is y equals 3x squared plus 1 a linear equation?
No. Y=3X2+1 is a Binomial Equation.
What is the x intercept for y equals -3x2 plus 12x-9?
1 and 3

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).
3x2 - y 6?
3x2-y=6 3x2-y=6
Does y equals 3x2 plus 2x-3 represent a function?
Yes.
Is y equals 3x squared plus 1 a linear equation?
No. Y=3X2+1 is a Binomial Equation.

-2
What is the x intercept for y equals -3x2 plus 12x-9?
1 and 3
What is the ordered pair for y equals 3x2 plus 24x plus 50?
