The first Weather Bureau Office to open in Arizona was in Yuma where the duties were transferred from the Army at Fort Yuma in July 1891. Tucson followed in September of that year, and it was not until four years later that the small community of Phoenix rated a full station.
Different types of graphs depend on the type of function that is graphed. The eight most commonly used graphs are linear, power, quadratic, polynomial, rational, exponential, logarithmic, and sinusoidal. Each has a unique graph that is easy to visually differentiate from the rest.
Quadratic Functions: We have learned three forms of quadratic functions-Vertex Form: -Factored form: -Standard Form: When given a graph like the one below we can write the equation for that quadratic in all three forms. You can start with any form but for this example we will start with vertex form.
