Answer:

Step-by-step explanation:

Data:
L₀ = 24 g
L = 20 g
k = 0.000 11 yr⁻¹
Calculation:

y^2 = x isn't a function because there is at least one value of x that produces multiple values of y. In fact, any x value greater than 0 yields two y values. If x = 0, then y = 0 is the only solution. ... Graphically, the equation fails the vertical line test, which is another way to determine that it is not a function.
