Our equation is in standard form to begin with y=ax 2 bxc;1 Introduction The composition of two functions g and f is the new function we get by performing f first, and then performing g For example, if we let f be the function given by f(x) = x2 and let g be the function given by g(x) = x3, then the composition of g with f is called gf and is worked outAnswer by robertb(5643) (Show Source)
An alternate approach to finding the vertex is to rewrite the quadratic function in the form f (x) = a (x − h) 2 k When in this form, the vertex is (h, k) and can be read directly from the equation To obtain this form, take f (x) = a x 2 b x c and complete the square A quadratic function is a function of degree two The graph of a quadratic function is a parabola The general form of a quadratic function is f(x) = ax2 bx c where a, b, and c are real numbers and a ≠ 0 The standard form of a quadratic function is f(x) = a(x − h)2 kQuestion This question is from textbook 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 values for x in example 1 they have 7 values for x, but in example 2 they have 5 values for x so how do you know how many numbers to chose forthe value of x?

The function p(x) = –8x2 – 64x can be written in vertex form p(x) = a(x – h)2 k, where a =, h =, and k = To graph the function p, reflect the graph of f(x) = x2 across the xaxis, vertically stretch the graph by a factor of 8, shift the graph units, and then shift the graph unitsPlugging these values into the general form f(x) = a f b(x − h) k where f(x) = , we get f(x) = 4 3 This can be simplified to f(x) = 3 _____ The mapping rule is useful when graphing functions with transformations Any point (x, y) of a parent function becomes ( h, ay k)The vertex form of a quadratic is given by y = a(x – h) 2 k, where (h, k) is the vertex The "a" in the vertex form is the same "a" as in y = ax 2 bx c (that is, both a's have exactly the same value) The sign on "a" tells you whether the quadratic opens up or opens down

F(x)=a(x−h)2k{\displaystyle f(x)=a(xh)^{2}k\,\!}is called the vertex form, where hand kare the xand ycoordinates of the vertex, respectively The coefficient ais the same value in all three forms To convert the standard formto factored form, one needs only the quadratic formulato determine the two roots r1and r2Parabolas The Vertex Form of a Parabola The formula for the vertex form of a parabola is f(x) = a(x h)2 k where a = vertical stretch or shrink of the parabola and (h, k) are the (x, y) coordinates of the vertex of the parabola h = the xcoordinate and k = the ycoordinateSo let's put that into this form of the equation f (x) = a (xh)2 k f (x) = a (x−1)2 1 Then we calculate "a" We know the point (0, 15) so f (0) = 15 And a (x−1)2 1 at x=0 is f (0) = a (0−1)2 1 They are both f (0) so make them equal a (0−1)2 1 = 15 Simplify a 1 = 15 a = 05
