Question

20/22
does the graph represent linear or nonlinear function?
it is a linear function,
because the graph forms by two straight lines.
it is a nonlinear function, because the graph is
a v-shape which is an absolute value function.
it is a linear function, because the domain value
is not repeating.
it is a linear function, because it passes the
vertical line test

Explanation:

A linear function has a constant rate of change and its graph is a single straight line. The given graph is a V-shape, which is the graph of an absolute value function. This function does not have a constant rate of change across its entire domain, so it is nonlinear. The vertical line test only confirms it is a function, not a linear one; non-repeating domain values also just confirm it is a function, not linear.

Answer:

It is a nonlinear function, because the graph is a V-shape which is an absolute value function.
