Question 1141345
---------------
The function f is defined by f(x)= k/x +3, where k is a constant. Find k, if the graph of f passes through the point (3/4 ,0).
--------------



{{{f(x)=k/x+3}}}


{{{f(x)-3=k/x}}}


{{{x(f(x)-3)=k}}}


{{{k=x(f(x)-3)}}}

-

Find k for point   ( 3/4,  0 ).
{{{k=(3/4)(-3)}}}


{{{highlight(k=-9/4)}}}
