Answer:
Both are straight, horizontal lines with 0 slope: y=4 and y=2. See attached graph.
Explanation:
f(x)=2^2
This is actually not a function of x. 2^2 = 4. F(x) = 4 for all values of x. Plotted, it will be a straight, horizontal line at y = 4.
f(x)=|2|
This is also not a function of x. f(x) = 2 for all values of x. It is also a horizontal line, but now at y=2.
See the attached graph.
