For what values of x is the function f(x)=x^2-4x-5 increasing?

1 answer:

4 0

Ok so differentiate the function, then set it as an inequality, if the function is increasing the gradient is positive >0 (so just make the differentiated function more than 0 to solve for the set of values of x) :)

For this case we have the following expression:
(5c ^ 2-15c ^ 3) / (20c ^ 2d + 25c ^ 2)
We make common factor c ^ 2:
(c ^ 2 (5-15c)) / (c ^ 2 (20d + 25))
We do common factor 5:
(5c ^ 2 (1-3c)) / (5c ^ 2 (4d + 5))
Canceling similar terms we have:
(1-3c) / (4d + 5)
Answer:
The simplified expression is given by:
(1-3c) / (4d + 5)
