Explanation / Answer

f(x)= x2

roots of f(x)

x2=0

x=0

axis of symmetry, x=0

g(x)=(x-8)2

roots

x-8=0

x=8

axis of symmetry x=8

h(x)= (x-8)2+9

Zeroes, h(x)=0

x-8=+-3i

No real zeroes

Axis of symmetry, x-8=0

x=8

p(x)=6(x-8)2+9

roots

6(x-8)2+9=0

no real zeroes

axis of symmetry x-8=0

x=8
