2252.2. Function concept recess: growth-decrease; biggest-smallest value;value interval.

Write the correct answer!

Given quadratic function y=2x^2 and two point A(-2;8) and B(1;2). Which of these points belong to graphic, which grows, and which - to decreasing part? Write the specific letter (if the points is not growing or decreasing, type 0)

Check the correct answer!

Is any of these points is functions minimum/maximum?
Point (0;0) is graphics:
Square function
Function concept recess: growth-decrease; biggest-smallest value;value interval.
