f(x)=2-3x Evaluate f(0) so we substitute the value of x=0, f(0) =2-3(0)=2
So f(0)= 2 ,then option C is correct.
2.for finding Which ordered pair is the turning point of the graph of f(x)= |x-4| we put f(x) =y= 0
|x-4|=0 ,x= 4 at y= 0 so the turning point of the graph of f(x)= |x-4| is (4,0) . option A is correct .
