## Algebra and Trigonometry 10th Edition

We are given the function: $h(x)=[[x+3]]$ denotes the greatest integer less than or equal to $x+3$. a) $h(-2)=[[-2+3]]=[[1]]=1$ b) $h\left(\dfrac{1}{2}\right)=[[0.5+3]]=[[3.5]]=3$ c) $h(4.2)=[[4.2+3]]=[[7.2]]=7$ d) $h\left(-21.6\right)=[[-21.6+3]]=[[-18.6]]=-19$
