Here we asked to compute G composed with G of X, which means take the function G of X, plug it in for X in itself, so what we'll do is take two X plus 7 and plug that in for X in the function two X plus 7. So out comes the X in goes the two X plus 7. And there we will use parentheses appropriately because it is multiplication. And then we'll simplify by distributing and then collecting like terms to get four X plus 14 plus 7, and then four X plus 21. So we took G of X plugged it in for X in itself and simplified.
