Answer :
plug the -4 into equation
f(-4) = 5(-4) -3
multiply 5•-4= -20
then subtract -20-3
when you have two negatives you add
= -23
[tex]f ( - 4) = 5( - 4) - 3 = - 23[/tex]
f(-4) = 5(-4) -3
multiply 5•-4= -20
then subtract -20-3
when you have two negatives you add
= -23
[tex]f ( - 4) = 5( - 4) - 3 = - 23[/tex]
