Question

Function and relation!
Help me please!

Answer 1

\[f(x)=2x^2 +1 for x \in -4 \le x \le5\]

\[g(x)=3-x for x \in R+\]

Answer 2

what are the domain and range of (f+g)(x) and (f*g)(x)??

Answer 3

this question is part of the composite function :)

Answer 4

Domain is the set from which may come the permissible values of x for the function right?
since both
f+g
and
fg
involve f and g, value of x must be in both domains. Does that give you a clearer idea?

Answer 5

yehh but i am not sure if i am doing right?
i got 0<=x<=6 for both f and g function.
do you think i am the right track?
