Given g(x) = –2x – 1, find g(3a).

G(3a)=-2(3a)-1

= -6a-1

= -5

is this right or do I just stop at -6a-1

Just stop at -6a-1

Also, let me add this.

If you have -6-1 (without the "a") that would be -7. Not -5.

But -6a-1 is the correct answer for this problem.

Matt

thank you for clearing this up for me.

:-) Glad I could help.
