(C). Function is not linear and range of change is not constant. So, we have to calculate average rate of change, which is slope of secant line. Thus, average rate of change of h(x) is the greatest.

Which has the greater rate of change?
1 Expert Answer
Rate of change can be either positive (acceleration) or negative (deceleration). Therefore, it is the magnitude (absolute value) that determines the “amount” of rate of change. Bottom line: -4 is a greater rate of change than +2 (assuming the units are the same in both instances).
Which function has a rate of change?
Linear functions feature a constant rate of change. This is called the slope. The slope can be seen in the table, the equation, and the graph for a line.
Which function is changing more quickly?
There are two types of rates of change of a function. An exponential rate of change increases or decreases more and more quickly, while the linear rate of change increases or decreases very steadily.
Which two functions have the same rate of change?
You simply need two functions that intersect at x=0 and x=2 . An example would be y=x2−1 and y=2x−1 . So the rates of change are equal.
What is average rate of change?
What is average rate of change? It is a measure of how much the function changed per unit, on average, over that interval . It is derived from the slope of the straight line connecting the interval’s endpoints on the function’s graph. Want to learn more about average rate of change?
What is the formula to find the rate of change?
To find the average rate of change, we divide the change in y (output) by the change in x (input) . And visually, all we are doing is calculating the slope of the secant line passing between two points.
What is a linear rate of change?
Definition: A linear function is a function that has a constant rate of change and can be represented by the equation y = mx + b , where m and b are constants. ... If we take the change in x to be a one unit increase (e.g., from x to x + 1), then a linear function will have a corresponding constant change in the variable y.
What is the rate of change on a graph?
The rate of change between two points on a curve can be approximated by calculating the change between two points. Notice that the numerator is the overall change in y, and the denominator is the overall change in x.
What is positive change rate?
A positive rate of change means that the quantity you are measuring is increasing over time , and a negative rate of change means that it is decreasing over time.
What is the rate of change of exponential function?
In an exponential function, increasing $x$ by 1 causes a change in $y$ by the same factor, called the growth rate. To get the next $y$, take the previous $y$ and multiply by 2. In a linear function, the rate of change is constant. In an exponential function the rate of change is proportional to the $y$-value .
How do you determine which function is greater?
There’s only one way in general: plug in a number and see what you get. If f(x)>g(x) for that value of x, then f will be larger than g until they intersect again.
How do you compare values in a function?
In the graph, the y -intercept is 5 and the slope is 1 . So, for x=0 , the function shown in the graph has a greater value. Also, since the slope is positive, it’s increasing. However, if you look at the values in the table, you will see that the y -values are equal to the square of x .
What is the minimum value?
The minimum value of a function is the place where the graph has a vertex at its lowest point . In the real world, you can use the minimum value of a quadratic function to determine minimum cost or area.
