What is the vertex of the quadratic y -2x2 plus 4x-1?
It is (1, 1).
What is the function y equals ax2 plus bx plus c?
It is a quadratic function which represents a parabola.
What is the vertex of the function y equals x squared plus 4?
The vertex is at the point (0, 4).
Is 3x plus 27 equals 8 a quadratic function?
No it is a linear one. X^2 = quadratic, x = linear. So if the equation doesn't have an x squared, then it is not quadratic.
What quadratic function would be used to solve -2x2 plus 9x equals 12?
-2x2 + 9x - 12 = 0Then apply the quadratic formula.
What is the vertex of the quadratic y -2x2 plus 4x-1?
It is (1, 1).
In the vertex form of a quadratic function y equals a the quantity of x-b squared plus c what does the b tell you about the graph?
The standard form of the quadratic function in (x - b)2 + c, has a vertex of (b, c). Thus, b is the units shifted to the right of the y-axis, and c is the units shifted above the x-axis.
What is the function y equals ax2 plus bx plus c?
It is a quadratic function which represents a parabola.
What is the vertex of the function y equals x squared plus 4?
The vertex is at the point (0, 4).
How do you find the quadratic function of y equals 7x2 plus 2x plus 11?
With difficulty because the discriminant of the quadratic equation is less than zero meaning it has no solutions
What is the difference between quadratic function and quadratic formula?
A quadratic function is a function where a variable is raised to the second degree (2). Examples would be x2, or for more complexity, 2x2+4x+16. The quadratic formula is a way of finding the roots of a quadratic function, or where the parabola crosses the x-axis. There are many ways of finding roots, but the quadratic formula will always work for any quadratic function. In the form ax2+bx+c, the Quadratic Formula looks like this: x=-b±√b2-4ac _________ 2a The plus-minus means that there can 2 solutions.
Is 3x plus 27 equals 8 a quadratic function?
No it is a linear one. X^2 = quadratic, x = linear. So if the equation doesn't have an x squared, then it is not quadratic.
What quadratic function would be used to solve -2x2 plus 9x equals 12?
-2x2 + 9x - 12 = 0Then apply the quadratic formula.
What is the vertex of the quadratic equation y equals x squared minus x plus 72?
(1/2, 71 and 3/4)or(0.5, 71.75)
What is the vertex of the function y equals x2 plus 6x-5?
x = -3y = -14
What is the x coordinate of the vertex parabola defined by the following function 3x plus x plus 7x plus 4?
The given equation is not that of a parabola.
What is 2w2-17w plus 21?
2w2 - 17w + 21 is a quadratic expression which, when treated as a function of x, describes a parabola that intercepts the x-axis at the points (-1.5, 0) and (7, 0), and has a vertex at the point (4.25, -15.125). It's factors are (2w - 3), and (w - 7)
