Open circle what is it

Composition means that you can plug g x into f x. That is, you plug something in for x, then you plug that value into g, simplify, and then plug the result into f. A vertical compression or shrinking is the squeezing of the graph toward the x-axis.

When we multiply a function by a positive constant, we get a function whose graph is stretched or compressed vertically in relation to the graph of the original function. If the constant is greater than 1, we get a vertical stretch; if the constant is between 0 and 1, we get a vertical compression. Examples of Vertical Stretches and Shrinks looks like? When a is negative, then this vertical compression or vertical stretching of the graph is followed by a reflection across the x-axis.

Determining whether a relation is a function on a graph is relatively easy by using the vertical line test. If a vertical line crosses the relation on the graph only once in all locations, the relation is a function.

However, if a vertical line crosses the relation more than once, the relation is not a function. A WAY easier and faster , way to know if it is a function is to see if there are two of the same x-intercept which make a vertical line. If there is, then it is NOT a function. A relation where each element in the domain corresponds to exactly one element in the range.

While it was in operation, Open Circle reached over schools, 90 districts, and 16 states across the U. It also reached educators and students as far away as China and Uganda. In June , Open Circle discontinued its curriculum and professional development training, transitioning to a legacy program of the Wellesley Centers for Women. About Open Circle For over 34 successful years, Open Circle provided evidence-based social and emotional learning SEL curriculum and professional development for elementary schools.
