Question 1086573
1) f(x) = 2x -3
:
y = 2x -3
x = 2y -3
:
2y = x +3
:
2) f^-1(x) = (x +3) / 2
:
This graph show equation 1 as a red line and equation 2 as a green line
:
{{{ graph( 300, 200, -10, 10, -10, 10, 2x-3, (x+3)/2) }}}
:
the domain and range for equations 1 and 2 is (-infinity, +infinity)
:
