given:
f%28x%29=2x%5E2-3+and g%28x%29=4x
to find:
(f o g)(1) or f%28g%281%29%29

first find f%28g%28x%29%29

f%28g%28x%29%29=f%284x%29
f%28g%28x%29%29=2%284x%29%5E2-3
f%28g%28x%29%29=2%2816x%5E2%29-3
f%28g%28x%29%29=32x%5E2-3

then

f%28g%281%29%29=32%2A1%5E2-3
f%28g%281%29%29=32-3
f%28g%281%29%29=29
