Question 578237
-3/2 is the same as -1.5


So any number less than -1.5 will work. So numbers such as f = -2, f = -4 or f = -10 are all solutions since they are all less then -1.5



The graph looks like the following


{{{drawing(500,80,-11.5, 8.5,-10, 10,
number_line( 500, -11.5, 8.5),


arrow(-1.5,0,-11.5,0),
arrow(-1.5,0.30,-11.5,0.30),
arrow(-1.5,0.15,-11.5,0.15),
arrow(-1.5,-0.15,-11.5,-0.15),
arrow(-1.5,-0.30,-11.5,-0.30),




circle(-1.5,0,0.3),
circle(-1.5,0,0.3),
circle(-1.5,0,0.3),
circle(-1.5,0,0.3-0.02)
)}}}


Take note that the endpoint is an open circle.
