27 days 7 hours 43 minutes and 11.6 seconds
Explanation:
(f o g)(x)
= f[g(x)]
= f(3x + 7)
= 5(3x + 7) - 4
= 15x + 31.
When (f o g)(k) = 7, 15k + 31 = 7.
=> 15k = -24, k = -8/5 = -1.6.
Answer:
here's the proof
Explanation:
x-1=0
x=1
so
f(x)=x⁴-2x³+x²-x+1
f(1)=1⁴-2.1³+1²-1+1
f(1)1-2+1-1+1
f(1)=2-2
f(1)=0
as we know When f(c)=0 then x−c is a factor of f(x)
hence x-1 is a factor of x⁴-2x³+x²-x+1
