Learning Task 1. Tell whether each picture models a quadratic function or not. Justify your answer.
GIVEN
Answer
WHY?

The picture for this question is given below.

All of them models quadratic function.

Step-by-step explanation: A quadratic function is of the form

f(x) = ax² + bx + c, with coefficient a≠0.

This function has a U-shape graphic called parabola. It has a vertex, i.e., a point where the curve changes, which is "classified" as minimum, if the parabola opens up; and as maximum, if the parabola opens down.

The y-intercepts are the points where the curve touches the y-axis and x-intercepts, if they exist, are the roots of the function.

The three pictures below shows three U-shaped curves opening down. This means the three parabolas are representation of 3 different quadratic functions, with a 3 vertex points that are maximum.

water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic. at this point, equilibrium is reached. in an isotonic solution, the flow of water in and out of the cell is happening at the same rate.
