i so dont get this! what about find f(-4) for the function below f(x)=-5|x|
did you get a wrong answer? or how did you try to solve it?
f(-4) is shorthand for evaluate f when x = -4. So just substitute -4 for x
The absolute value of -4 would be 4 and 4 times -5 equals -20
thank you guys! this poor momma needs a refresher course!
