Quadratic ApplicationsQuadratic problems can basically ask you one of two main questions:1) Find the vertex
– words like max/min, highest/lowest, most/least etc
« how??» Factored form
» Standard form
» Vertex form
2) Solve the equation for one of the variables> you will be given a value for one variable and have to solve
for the other
> sub in the known value and solve
EASY type given the independent variable (x, time, etc) plug in and calculate
HARDer type given dependent variable (y, height, profit etc) plug in, set equation = 0 and solve
« how?» Factored form
» Standard form
» Vertex form
