A function g is given by g(x)=x^2+2. Find g(−1),g(0),g(9),g(a+h), and (g(x+h)-g(x))/h
For the following quadratic function, (a) find the vertex and the line of symmetry, (b) state whether the parabola opens upward or downward, and (c) find its x-intercept(s), if they exist. f(x)=x^2−14x+13 a) The vertex of the parabola is (7,−36). (Type an ordered pair.) The line is the line of symmetry of the function f(x)=x^2−14x+13 (Type an equation.)
