How does a function differ from an equation?
A function is a rule to calculate a variable, based on one or more other variables. It may be written as an equation, but unlike a generic equation, in a function, for every value of the input variables, it may ONLY have ONE result.
Why do scientists create graphs?
Scientists create graphs to visually represent data and to better understand patterns and relationships within the data. Graphs allow scientists to analyze and interpret information more easily, identify trends, and communicate their findings to a wider audience. Graphs also help scientists make predictions and draw conclusions based on the data they have collected.
What 3 things do all graphs and data tables have to have in addition to data?
A title, labeled axes (for graphs), markings on the axes (again, for graphs) and units of measurement. You could use any of the above, based on your context
What is the degree of a polynomial equation is based on?
The highest power in the equation.
Explain how graphs are used and what their advantages are?
Graphs give a very rapid visual of trends that may exist in data. This trend may be observed and formulae may be derived based on proportionality of 2 variables (one being controlled at a time)
