Graphing quadratics: standard form Algebra (video) Khan Academy

WebThis set of printable worksheets requires high school students to write the quadratic function using the information provided in the graph. If the x-intercepts are known from the graph, apply intercept form to find the quadratic function. If the vertex and a point on the parabola are known, apply vertex form. WebApr 10, 2015 · Apr 10, 2015. Given f (x) = − x2 +14x − 48. f '(x) = −2x +14. for critical point (s) f '(x) = 0. −2x + 14 = 0. x = 7 for the only critical point. We can either use our knowledge of quadratics or take the second derivative ( f ''(x) = − 2 → slope is always decreasing) to observe that this point is a maximum. Therefore f (x) has a ... matt hawkins inspector
