Answer:
-246
Step-by-step explanation:
Add all the numbers together and divide by the amount of numbers added to find the mean. -246 is the only right answer.
Since we know f(x)=11 all we need to do is substitute and solve. so
11=-2x+3 subtract 3 from both sides
8=-2x divide both sides by -2
-4=x
sub back in to check
-2(-4)+3=8+3=11 looks good
