[-/2 Points]
?
WANEFMAC8 1.2.001. This exercise is based on the following functions.
f(x)=x^(2)+2 with domain (-\infty ,\infty )
g(x)=x-2 with domain (-\infty ,\infty )
h(x)=x+5 with domain [18,\infty )
u(x)=\sqrt(x+18) with domain [-18,0)
v(x)=\sqrt(18-x) with domain [0,18]
(a) Write a formula for the indicated function.
s=f+g
s(x)=
?
(b) Give the domain. (Enter your answer using interval notation.)
?
(c) Specify the function's value at the given point
a=-5
, if defined. (If an ans
s(-5)=
