The number of animal species N of a certain body length as a

The number of animal species, N, of a certain body length as a function of the body length, L, is N = A/L^4. (a) What is the exponent of this power function? P = help (numbers) (b) Assuming the constant A is positive, which graph A-D best matches the graph of this power function?

Solution

N = A / L^4

exponent of this power function is -4

since exponent in denominator is 4

when it comes in numerator it becomes -4

b) graph c is the graph of the power function
