1 You found h ( 2) Instead we want to find h ′ ( 2) First, take the derivative of h ( x) = f ( x) g ( x) with respect to x and use the given values above to find h ′ ( 2) So h ′ ( x) = f ′ ( x) g ′ ( x) and we will let x = 2 to obtain h ′ ( 2) = f ′ ( 2) g ′ ( 2) = 2 ( − 5) = − 3 Thus h ′ ( 2 Article Summary X To find the vertex of a quadratic equation, start by identifying the values of a, b, and c Then, use the vertex formula to figure out the xvalue of the vertex To do this, plug in the relevant values to find x, then substitute the values for a and b to get the xvalueExplore the parent graph y=x^3 Experiment with the values of a, h, and k What happens to the graph as these values change?

Vertex form is y=a(xh) 2 k The vertex of an equation in vertex form is (h,k) In vertex form, we have x MINUS h So if we're trying to just pick out 'h', we need to flip the sign that's in front of itH(x) = f (x)g (x) h ( x) = f ( x) g ( x) Since f (x)gx f ( x) g x is constant with respect to f f, the derivative of f (x)gx f ( x) g x with respect to f f is 0 0 0 0Y = a(x −h)4 k The turning point is at (h,k) When sketching quartic graphs of the form y = a(x − h)4 k, first identify the turning point To add further detail to the graph, the xaxis and yaxis intercepts are found Example 2 Sketch the graph of the function y = (x − 2)4 − 1 Cambridge University Press ¥ Uncorrected Sample Pages ¥
