Question

F : x > 3 - x
what is the value of F(7)

Answer 1

f(7)=3-7=-4 replace x with 7

Answer 2

7>-4 and thus 11>0

Answer 3

lost me on the last one

Answer 4

i am guessing that the the function notation is
\[F: x\mapsto 3-x\] and therefore as you said
\[x\mapsto 3-7=-4\] but then
\[11\mapsto 3-11=-7\] right?
