If a horizontal line intersects the graph of f(x)inmorethanonepoint, then f(x)isnotonetoone The reason f(x)wouldnotbeonetooneisthatthegraphwouldcontain two points that have the same second coordinate – for example, (2,3) and (4,3) That would mean that f(2) and f To find f (xh) substitute x = x h into the function f (x h) = (x h)2 − 2(x h) 5 now distribute the brackets f (x h) = x2 2hx h2 − 2x − 2h 5 which may be expressed as f (x h) = x2 2x(h −1) h2 − 2h 5 Answer linkThe discriminant in the Quadratic Formula is b 2 – 4ac Take the negative of this to get the reverse of the subtraction –(b 2 – 4ac) = 4ac – b 2 The formula for h has a denominator of 2a;
K In this lesson you will learn about graphs of equations of the form y = a ( x − h) 2 k For example, you will look at equations such as y = 3 x 2, y = − 2 x 2, and y = 2 ( x 1) 2 3, and compare them to y = x 2 You will also learn about roots of quadratic equations and how the values of a, h, and k affect the number of rootsThe standard form of a quadratic function presents the function in the form f (x)= a(x−h)2 k f ( x) = a ( x − h) 2 k where (h, k) ( h, k) is the vertex Because the vertex appears in the standard form of the quadratic function, this form is also known as the vertex form of a quadratic function The standard form is useful forSOLUTION solving quadratic functions of the form f(x)=a(xh)2k(that 2 is a squared) i know how to get the value of a,h,k, but i dont know what they mean when they say choose some valu
