Can write a quadratic function given key features in the form of ordered pairs 12: Write an equation of each quadratic function, in vertex form, with the given vertex and point

a) Vertex at (1.2) and passes through the point (3.4)

b) Vertex at (-5, -1) and passes through the point (6.3)

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
