A point on a curve is considered a relative minimum if the function is defined at that point and the function has equal or greater values an infinitesimal distance on both sides of the point.
Q. What are the coordinates of the minimum point of a parabola whose equation is y x2 2?
The parabola y=x2 has a vertex at the origin. The parabola y=x2+2 has endured a vertical translation 2 units up, so the new vertex becomes (0,2) . The vertex is always the lowest point of a quadratic function of the form y=ax2+bx+c with a>1 . Therefore, the minimum point is (0,2) .

Q. How do you find the lowest point of a parabola?
In the graph, the highest or lowest point of a parabola is the vertex. The vertex of the graph of y=x2 is (0,0). If a>0 in f(x)=ax2+bx+c, the parabola opens upward. In this case the vertex is the minimum, or lowest point, of the parabola.

vertex
Q. How do you find the equation of a curve?
Write the slope-intercept form for linear equations. Substititute the y-intercept into the slope-intercept equation. Substitute both the x-intercept point and the y-intercept into the equation to solve for slope. Rewrite by substituting the values of and into the y-intercept form.
Q. How do you find the minimum and maximum of a quadratic equation?
Finding max/min: There are two ways to find the absolute maximum/minimum value for f(x) = ax2 + bx + c: Put the quadratic in standard form f(x) = a(x − h)2 + k, and the absolute maximum/minimum value is k and it occurs at x = h. If a > 0, then the parabola opens up, and it is a minimum functional value of f.
Q. What is the minimum value in math?
Minimum, in mathematics, point at which the value of a function is less than or equal to the value at any nearby point (local minimum) or at any point (absolute minimum); see extremum. …
Q. How do you find the maximum of an equation?
If you have the graph, or can draw the graph, the maximum is just the y value at the vertex of the graph. If you are unable to draw a graph, there are formulas you can use to find the maximum. If you are given the formula y = ax2 + bx + c, then you can find the maximum value using the formula max = c – (b2 / 4a).
Q. What are key features of parabolas?
One important feature of the graph is that it has an extreme point, called the vertex. If the parabola opens up, the vertex represents the lowest point on the graph, or the minimum value of the quadratic function. If the parabola opens down, the vertex represents the highest point on the graph, or the maximum value.
Q. How do you know if it’s a parabola?
Let’s look at a few key points about these patterns:
- If the x is squared, the parabola is vertical (opens up or down). If the y is squared, it is horizontal (opens left or right).
- If a is positive, the parabola opens up or to the right. If it is negative, it opens down or to the left.
- The vertex is at (h, k).
