x intercepts of quadratic function

Find the x - intercepts of the graph represented by the quadratic function f ( x ) = x 2 - 5 x + 4. => 4 and 1 or - 4 and 1 or 4 and - 1 or - 4 and - 1..

Which quadratic function best represents the graph? => y = - x 2 - 2 x + 1 or y = x 2 - 2 x + 1 or y = x 2 + 2 x + 1 or y = - x 2 + 2 x + 1..

Identify the quadratic function that best represents the graph shown. => y = - x 2 - 2 or y = - x 2 - 1 or y = - x 2 + 1 or y = - x 2 + 2..

Determine which of the graphs represent a quadratic function. => Graph 1 and Graph 4 or Graph 1 only or Graph 1 and Graph 3 or Graph 4 only..

Type 1 - Equations of the form In such equations, put x n = t then the equation reduces to at 2 + bt + c = 0. Solve for t and then obtain the value of x..

Let a and b be the roots of the equation (i), Then x = a and x = b Since a and b are the roots of the equations (i) and (ii), both the equations are identical. Dividing equation (i) by 'a', we get The equations (ii) and (iii) are identica..

A function f : A B is said to be an even function if f(x) = f(-x) for all x A. The domain and range of f depends on the definition of the function. Examples of even function are y = cosx, y = x 2 , y = secx A polynomia..
