Question 256235
 I know the function for linear equations is y=k/x . the question I am having trouble with is exactly as written: f(x)=4/x graph the inverse variation function. what is "f" 
:
f(x) = y, so write the equation
y = 4/x
To find the inverse, swap x and y and solve for y
x = 4/y
Multiply both sides by y
xy = 4
divide both sides by x
y = 4/x, which means the inverse is the same as the original equation
:
The graph
{{{ graph( 300, 200, -6, 5, -10, 10, 4/x) }}}
