Hello,
Answer D:
the roots are -5,1+4i,1-4i,-4i,4i.
Answer:
No
Step-by-step explanation:
To obtain the inverse function
let y = f(x) and rearrange making x the subject, that is
y = 3x + 1 ( subtract 1 from both sides )
y - 1 = 3x ( divide both sides by 3 )
= x
Change y back into terms of x, thus
(x) = 
First deal withe the numerator 4 x^2
square root of 4 is 2 and square root of x^2 = x
so square root of 4x^2 is 2x
as for the 3y we can write it as √(3y)
so answer is 2x / √(3y)
Answer:
80,000,000>20,000
Step-by-step explanation:
10^7 is 10,000,000
10,000,000 x 8 = 80,000,000
10^4 is 10,000
10,000 x 2 = 20,000
80,000,000>20,000
