The value of x is x and x
Step-by-step explanation:
Factorisation is not possible in this case since the 2 pairs available will not be giving the same outcome as required in factorisation.
This is a quadratic equation
x² + x² – 3x – 3 = 0
2x² - 3x - 3 = 0
<u>Quadratic formula:</u>
a=2
b= -3
x= -3
=
= 2.186
or
=
= -0.686
Therefore, the value of x is,
x and x

Answer:
Increasing if f' >0 and decreasing if f'<0
Step-by-step explanation:
Difference quotient got by getting
will be greater than 0 if function is increasing otherwise negative
Here h is a small positive value.
In other words, we find that whenever first derivative of a function f(x) is positive the function is increasing.
Here given that for x1, x2 where x1<x2, we have
if f(x1) <f(x2) then the function is decreasing.
Or if x1<x2 and if f(x1) >f(x2) for all x1, and x2 in I the open interval we say f(x) is decreasing in I.
