y = 2x^2 + x -1
If you know calculus you can find the minimum or maximum when the slope of the equation is zero. This is the first derivative of y with respect to x
dy/dx = 4x +1 = 0
4x = -1
x = -1/4
y = 2 (-1/4)^2 -1/4 -1 = 1/8-1/4-1 = 1/8 - 2/8 - 8/8 = -9/8 minimum = -1.125
What else can I help you with?
What is the vertex of the parabola y equals x2 plus 8x plus 5?
The vertex has a minimum value of (-4, -11)
Is x2 plus y2 equals 4 a function?
No. By definition, a function has a single unique value for every value passed into it. The equation given here describes a circle, which can not be rearranged to meet this condition.
Are the function F of x equals -2over 3 plus 1 and determine the slope explain?
The function that is given has a constant value and therefore, its slope is 0.
If a plus b equals 6 what is the value of 3a plus 3b?
If a + b = 6, what is the value of 3a + 3b?
What is the maximum or minimum value of y equals x to the power of 2 minus 4x plus 7?
It has an absolute minimum at the point (2,3). It has no maximum but the ends of the graph both approach infinity.
What are the minimum and maximum values for the objective function C equals 3x plus y?
The answer will depend on the ranges for x and y. If the ranges are not restricted, then C can have any value.

Is this equation a function y equals 3squared plus 2x minus 3 is this a function?
You can tell if an equation is a function if for any x value that you put into the function, you get only one y value. The equation you asked about is the equation of a line. It is a function.
