A number changes from 50 to 76. What type of percent change is this? Calculate the percent change.

7 0

This is a positive increase

You need to find the difference between 50 and 76 which is 26.
Then you do 26/50 which is 0.52. Multiply 0.52 by 100 and that leaves you with 52.

The percentage increase is 52%.

Answer:

<h3>50 is the old value and 76 is the new value. In this case we have a positive change (increase) of 52 percent because the new value is greater than the old value.</h3>

What is the average rate of change of f(x) = -x2 + 3x + 6 over the interval –3

Answer:

$\frac{\Delta y}{\Delta x} =\frac{f(x_2)-f(x_1)}{x_2-x_1} =\frac{6-(-12)}{3-(-3)} =\frac{18}{6}= 3$

Step-by-step explanation:

To find the average rate of change of a function over a given interval, basically you need to find the slope. The mathematical definition of the slope is very similar to the one we use every day. In mathematics, the slope is the relationship between the vertical and horizontal changes between two points on a surface or a line. In this sense, the slope can be found using the following expression:

$Average\hspace{3}rate\hspace{3}of\hspace{3}change=Slope=\frac{y_2-y_1}{x_2-x_1} =\frac{f(x_2)-f(x_1)}{x_2-x_1}$
