Question

f(x) = x+4 @loser66

Answer 1

\[f^-1(x) = -4 + x\]

Answer 2

if x =-3
then -4-3 is not 1

Answer 3

I checked on mathway again and the graph looks exactly like that with those points so I assumed when I did
-4 +0 = -4
and
-4 + 1 = -3
that it gave me the points
(-4, 0) and (-3, 1) because those show up on the graph

Answer 4

I even went back on the last two problems and tried that and it worked out, so I'm confused.
