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)=
