Is the equation a linear function or nonlinear function?

Linear function

Step-by-step explanation:

The best definition of a linear function is one whose highest x power is 1.

x is a linear function; the highest power of x is 1.

x^2 is not a linear function; the highest power of x is 2.

y = 0.5x - 1 is a linear function because the highest power of x is x^1.

i would have to say it is c.

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
