Does the rate of change have to be negative?
no... the sign indicates whether the rate of change is increasing or decreasing. It is only negative if the rate is decreasing over time.
What is X2-4 divided by x2 plus 3x plus 2 continuous or discontinuous?
The numerator function x2 - 4 and the denominator function x2 + 3x + 2 are both continuous functions of x for the entire x-axis. However, the quotient of these two functions is not continuous when the denominator function has the value of 0, because division by zero is not defined. The denominator function is 0 when x = -1 or -2. Therefore, the quotient function is not fully continuous over any intervals that include -1 or -2, but it is "piecewise continuous" over other intervals of the x-axis.
How do you show log x is convex?
Log x is defined only for x > 0. The first derivative of log x is 1/x, which, for x > 0 is also > 0 The second derivative of log x = -1/x2 is always negative over the valid domain for x. Together, these derivatives show that log x is a strictly monotonic increasing function of x and that its rate of increase is always decreasing. Consequently log x is convex.
Over the set of real numbers what is the domain of the composite function GF x?
The domain of your function is the set of real numbers.
What is the reflection through an x axis?
All y-values in the function are multiplied by -1. This function is 'flipped' over the x-axis.
Is global wealth increasing or decreasing over time?
decreasing per capita
Gun deaths increasing or decreasing in US?

Are the number of wars in the world increasing or decreasing?
The number of interstate wars (wars betweens countries) has been decreasing over time. However, the number of intrastate wars (civil wars) have been increasing over time.
Does the rate of change have to be negative?
no... the sign indicates whether the rate of change is increasing or decreasing. It is only negative if the rate is decreasing over time.
How do you identify the range of a function?
The range of a function is the interval (or intervals) over which the independent variable is valid, i.e. results in a valid value of the function.
Are kangaroos decreasing or increasing in numbers?
The majority of kangaroo species have an erratic population pattern, increasing and decreasing with environmental conditions. There are over 60 species of kangaroo, however, and many of the lesser-known species are decreasing in number, especially those in the wallaby family. But the larger creatures commonly recognised as kangaroos, such as Red kangaroos and Grey kangaroos, remain common and prolific.
When water changes from liquid to gas is the temperature decreasing or increasing?
It is increasing in temperature. When you put a pot of water over a lit stove, it evaporates into its gas form, water vapor, which can also be called steam.

What kind of changes would you expect to see in an ecosystem over time?
you would expect that the populations of animals are increasing or decreasing or because of no rainfall the plants will get dried.
How many lions live in the jungle?

How do you discuss trends that occur by looking at a graph?
When both axis' are increasing it is a positive correlation. When both are decreasing it is a negative correlation. When the dots are all over the place then there is no correlation.
What is a sales analysis report?
A sales analysis report basically shows the trends of sales that have occurred within a business over a period of time. This report will show you if sales are decreasing or increasing.
