Question

Consider this function. f(x)=6log2x-3 over which interval is function f increasing at the greatest rate?

1. diemkieu
The function increased at the highest rate in the interval [1/8, 1/2], as can be seen from the function value and its interval values.

### What is  maxima and minima?

A function’s maxima and minima are its highest and lowest values, respectively, either on the entire domain or inside a certain range. They are referred to as the function’s extrema collectively. The plural forms of maximum and minimum for a function are respectively known as maxima and minima.

### Why do we use maxima and minima?

The extreme values of a function—their maximum and minimum values—are referred to by the words maxima and minima. Maximum refers to the maximum value or amount that is feasible. A function’s biggest value within its range is known as its absolute maximum.

### According to the given information we have:

f(x)=6log2x-3
For the interval x ∈[2, 6]
f(x) ∈ [-0.678, 3]
For the interval x ∈ [1/8, 1/2]
f(x) ∈ [ -9.96, -5.32]
For the interval x ∈ [1, 2]
f(x) ∈ [-3, -0.67]
For the interval x∈ [1/2, 1]
f(x) ∈ [-5.32, -3]
The function increased at the highest rate in the interval [1/8, 1/2], as can be seen from the function value and its interval values.
