Graphs of Sine and Cosine 1.2 ... to a parabola is obtained through successive secant lines. Functions with Corners 2.1 Some examples of graphs with corners which I talked about in lecture. The ...
Given a function f(x), and two points on the curve (a, f(a)) and (b, f(b)) the line joining these two points is called a secant line of f. (Not to be confused with the trigonometric secant (sec) ...
All quadratic functions have the same type of curved graphs with a line of symmetry. The graph of the quadratic function \(y = ax^2 + bx + c \) has a minimum turning point when \(a \textgreater 0 ...
Find the equation of the line of symmetry and the coordinates of the turning point of the graph of \(y = x^2 – 6x + 4\) The coefficient of \(x^2\) is positive, so the graph will be a positive U ...
