Transcript text: We need to use common vocabulary when describing graphs:
a. Domain $\qquad$ The part of the graph with the lowest $y$-value
b. Range $\qquad$ All of the $y$-values that are needed to graph the function
c. Rate of Change $\qquad$ Where the $y$-value increases when $x$ increases.
d. Minimum $\qquad$ Where a graph crosses the $x$ axis
e. Increasing $\qquad$ The part of the graph with the highest $y$ value.
f. Decreasing $\qquad$ Where the $y$-value decreases when $x$ increases.
g. Maximum $\qquad$ All of the $x$-values that are needed to graph the function
h. x-Intercept $\qquad$ Where the $y$-value doesn't change when $x$ increases.
I. $y$-Intercept $\qquad$ The slope! How "steep" the line is. $\frac{\Delta y}{\Delta x}$
