The correct option is B). f(x)
The minimum value for y belongs to f(x) at x=0 and f(0)=(-2)
Step-by-step explanation:
The given two functions are f(x)= and g(x)=
To find which function got minimum value for y :
For function f(x)=
Using concept of Maxima and Minima,
Function : f(x)=
Differentiating the function we get,
f(x)=
Take f(x)=0
x=0
Therefore, f(x)=f(0)=0-2=(-2)
For function g(x)=
Using concept of Maxima and Minima,
Function : g(x)=
Differentiating the function we get,
g(x)=
Take g(x)=0
=0
x=0
Therefore, g(x)=g(0)=0+1=1
<em>Thus, The minimum value for y belongs to f(x) at x=0 and f(0)=(-2)</em>
The correct option is B). f(x)
