Question

5) Given
f(x)=−x2+6x−11
, find
f(4x−1)

a) −162+32x−18

b) −82+2x−8

c) 22+6x−5

d) 4x2+7x−9

Determine all the roots
f(x)=9x2−18x2+6x

a) x=1,x=5+(√5)3,x=5−(√5)3
x=1,x=5+(5)3,x=5−(5)3

b) x=0,x=1+(√2)2,x=1−(√2)3
x=0,x=1+(2)2,x=1−(2)3

c) x=1,x=2+(√2)2,x=2−(√2)3
x=1,x=2+(2)2,x=2−(2)3

d) x=0,x=3+(√3)3,x=3−(√3)3
x=0,x=3+(3)3,x=3−(3)3
