amistre64 · Answer

if its a graph; go over to x = -3 and then go up or down to find the curve; then see what y value you get from it

anonymous · Answer

So, at x=-3 f(x)= 4, but the g(x) is and absolute value graph only going up to 3. This hmwk is only and I put in DNE (does not exist) but it told me it was wrong and that the answer was -1.

i did :)

f(x) = -x+1

g(x) = -|x| + 3

g(f(x)) = -|-x+1| +3 ; at x=-3 we get:

-|--3+1|+3

-|4| + 3

-4 + 3 = -1
