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 \(a \textgreater 0 \) ...

An equation of the form \(y = mx + c\) where \(m\) and \(c\) are numbers, gives a straight line when values of \(x\) and corresponding values of \(y\) are plotted on a grid. A straight line is a ...

Abstract. For f analytic and close to convex in D = {z : |z| < 1}, we give sharp estimates for the logarithmic coefficients γn of f defined by log f ( z ) z = 2 ∑ n = 1 ∞ γ n z n when n = 1, 2, 3.
