"a "and "b^2-4ac" must be negetive
Given function : 
.
We need to find the values of f(-2).
In order to find the value of f(-2), we need to plug x=-2 in the given fucntion .
Replacing x by -2, we get
We get (-2)^2 = -2 *-2*-2=-8 and (-2)^2 = -2 * -2 = 4.
.
f(-2) = -160 +12.
f(-2) = -148.
Therefore, correct option would be option D. That is f(-2)=-148.
Step-by-step explanation:
The parent function of the functions of the form f(x)=√x−a+b is f(x)=√x . Note that the domain of f(x)=√x is x≥0 and the range is y≥0 . The graph of f(x)=√x−a+b can be obtained by translating the graph of f(x)=√x to a units to the right and then b units up.
