Question 86143: I am just wanting to make sure I am doing these right.
if f (x) = 5x - 1, find the following:
f (a-2)
f(a-2)=5(a-2)-1
=5a-10-1
=5a-9

if f (x) = 4x - 3, find the following:
f (-1)
f(-1)=4(-1)-3
= -4-3
= -7

I am just wanting to make sure I am doing these right.
if f (x) = 5x - 1, find the following:
f (a-2)
f(a-2)=5(a-2)-1
=5a-10-1
=5a-9
if f (x) = 4x - 3, find the following:
f (-1)
f(-1)=4(-1)-3
= -4-3
= -7
LOOKS TO ME LIKE YOU KNOW WHAT YOU ARE DOING. I THINK THAT YOU ARE RIGHT ON!!! GOOD WORK!!!!!
Hope this helps-----ptaylor
