To make it increase, simply change the negative sign to positive
How to make a decreasing function to increase.
The graph of the function f(x) = -(x + 2)³ - 5 can be increased when the negative sign of the leading coefficient is changed. The negative sign in front of (x + 2)³ reflects the graph across the x-axis, resulting in a decreasing function.
To make it increase, simply change the negative sign to positive:
f(x) = (x + 2)³ - 5
Now, the graph of this function will be increasing.
Generally, to make a decreasing function to increase.
Identify the Leading Term:Look at the term with the highest power in your function. This is the leading term.Change the Sign:If the coefficient of the leading term is negative, change it to positive.
