Answer
Verbally, Algebraically, Numerically, and Graphically
Work Step by Step
Verbally
e.g. Double the number and add one.
Algebraically
$f(x)=2x+1$
Numerically
e.g. $\left[\begin{array}{l|lllll}
x & -1 & 0 & 1 & 2 & 3\\
\hline f(x) & -3 & 1 & 3 & 5 & 7
\end{array}\right]$
Graphically
- a graph with x on the horizontal axis, f(x) on the vertical.
The points on the graph are (x,f(x)), that is,
the y-coordinate is the function value of the x-coordinate.
