【题目】8 Given that the line of symmetry of the quadratic function is x-2. the minimum value of the function is 3 and the graph passcs through the point (-1. 5). then an analytical expression of the quadratic function is 相关知识点: ...
Many graphs have a line of symmetry that runs through the center of the graph, creating two perfectly identical halves. The formula to find the line of symmetry of a quadratic function is x=-b/2a, where a and b are determined from the standard form ax^2 + bx + c = 0.Understanding...
quadratic equations produce a U-shaped curve known as a parabola. The line of symmetry is an imaginary line which runs down the center of this parabola and cuts it into two equal halves. This line is commonly referred to as the axis of symmetry. It can be found quite...
When a quadratic is written in vertex form: f(x) = a(x-h)^2 + k Then x = h is axis of symmetry. Another example: g(x) = 2(x+6)^2 + 13 axis of symmetry is x = -6 Upvote • 0 Downvote Add comment Mark M. answered • 12/06/16 Tutor 5.0 (278)...
Find the vertex, the line of symmetry and the maximum/minimum value of x for the function f(x)=−2x2+2x+5. Maxima/Minima and the Vertex Whenever we need to find the maximum or the minimum of a quadratic equation, we can start by finding...
A horizontal line is a line that goes from left to right and is parallel to the horizon or x-axis. The equation of horizontal line will have only one variable. Learn symmetry of horizontal line at BYJU’S, with examples.
