This can be written using the linear function y x3. Percent increase and percent decrease are measures of percent change which is the extent to which something gains or loses valuePercent changes are useful to help people understand changes in a value over time. The conjugate is where we change the sign in the middle of two terms.
Lets look at some more examples of percent increase and decrease.
Form the table it is observed that the rate of change between x and y is 3. Subtract 100 from that. Another way to express this formula is fx 0 h fx 0h if h is used for x 1 x 0 and fx for y. They resolve the truth or falsity of such by mathematical proof.
