For the function ​g%28x%29=%281%2F3%29+x-8
​
find g%283%29%2Bg%28a%29
first find g%283%29
g%283%29=%281%2F3%29+3-8
g%283%29=%281%2Fcross%283%29%29+cross%283%29-8
g%283%29=1-8
g%283%29=-7

now find g%28a%29
g%28a%29=%281%2F3%29a-8
and you have

g%283%29%2Bg%28a%29=-7%2B%281%2F3%29a-8
g%283%29%2Bg%28a%29=%281%2F3%29a-15
