For the function ​g%28x%29=%281%2F2%29+x-2
​
find g%282%29%2Bg%28a%29
first find g%282%29
g%282%29=%281%2F2%29+2-2
g%282%29=%281%2Fcross%282%29%29+cross%282%29-2
g%282%29=1-2
g%283%29=-1

now find g%28a%29
g%28a%29=%281%2F2%29a-2
and you have

g%282%29%2Bg%28a%29=-1%2B%281%2F2%29a-2
g%282%29%2Bg%28a%29=%281%2F2%29a-3
