Final answer:
In logarithmic graphs, growth occurs (in the shape of the left half of an arch) when the value of x in the equation log_a(x) is increasing.
Step-by-step explanation:
In logarithmic graphs, growth occurs (in the shape of the left half of an arch) when the value of x in the equation loga(x) is increasing. This means that as x increases, the value of loga(x) also increases.
For example, let's consider the equation log10(x). If we plug in different values of x, we can see that as x increases, the value of log10(x) also increases:
- When x = 1, log10(1) = 0
- When x = 10, log10(10) = 1
- When x = 100, log10(100) = 2
So in the logarithmic graph of log10(x), we can see that as x increases, the graph moves upwards, forming the left half of an arch.
