Question

The height of a tree was 2/(5 ) of its current height before 2 years. If its height is 25 5/(6 )m now, What was its height before 2 years?

Answer 1

Answer:

you can find the minimum or maximum value algebraically by using the formula x = -b / 2a. This formula will give you the x-coordinate of the vertex. Simply replace the x in your original equation with the value of the x-coordinate and then solve for y.
