Answer:$+0Ry what is the meaning?
Step-by-step explanation:
We know
is an increasing function as when the value of x increases the value of y increases
And when the value of x decreases , the value of y also decreases.
Now if we have (x+a) or (x-a) instead of x, the function shall have a horizontal shift.
So it shall either move left or right but shall not flip.
So
and
are increasing functions.
Only when x becomes -x, that the function shall flip & shall become a decreasing function.
But then it must be - (x-a) or -(x+a) inside.
So
is also increasing
Only
is a decreasing function.
Option D) is the right answer.
Answer:
Option C is correct.
roots of the given equation ,
Step-by-step explanation:
Given the equation:
We can write this equation as:
A quadratic equation is in the form of ......[1] where a,b ,c are the coefficient and x is the variable,
the solution of the equation is given by;
On comparing given equation with equation [1] we get;
a = 3 , b = -4 and c =10
So, the solution of the given equation is given by;
or
or
[∴
Simplify:
therefore, the roots of the given equation are;
