Given g(x)=-x+6 Find g(-3)

Question

Help meeeeee please I need the answer 

Answer 1

Hi Lauren,

 

Sorry, I had begun typing this answer on my own and came in and saw it was answered! I just thought I'd type out my walk-through steps...

 

At any rate, be careful with making sure you account for negative signs!

 

In your question, the function was defined as:

g(x)=-x+6

 

So yes, when asked for g(-3) you do substitute the value "-3" in for "x."

But remember, the function includes a negative sign before the "x." So, when substituting "-3" in for "x," your function would read:

 

g(-3) = -(-3)+6

g(-3) = 3 + 6

g(-3) = 9

 

 

Answer 2

Hi, Lauren.

 

g(x) = - x+ 6

 

To find g(-3), just substitute -3 for x in the equation.

 

g(-3) = -(-3) + 6 = 9
