Find all rational roots for p(x)=0
Olenka [21]

Answer

C. (5/2, -1/3)

Step by step explanation

Here we use the rational root theorem.

The possible roots are

+1, +3, +5, +15, +1/2, +3/2, +5/2, +15/2, +1/3, +5/3, +1/6 and +5/6

We have to use the synthetic division to find the correct root of this function.

Here the roots are 5/2 and -1/3

Others are not roots of this function.

Let's check x = 5/2  with synthetic division.

5/2)   6   -13   13   -39   -15

-               15    5    45    15

           --------------------------

             6     2   18     6     0

Similarly x = -1/3 is also root of this function.

Answer: C. (5/2, -1/3)

Which statement is correct? A) 13/ 3 < 4.25 < 43 /10 B) 43 /10 < 13 /3 < 4.25 C) 4.25 < 13 /3 < 43/ 10 D) 4.25
Ivan
D. 4.25 < 43/10 < 13/3 
     
4.25   = 4.25
43/10 = 4.3
13/3   = 4.33

4.25 < 4.3 < 4.33

Which statement is true?
SVEN [57.7K]

Answer:

y=log_{1} x is not a logarithmic function because the base is equal to 1.

Step-by-step explanation:

A logarithmic function is of the form: y=log_{b}x

For a logarithmic function to exist, we must fulfill certain conditions. The conditions are

i. The base, b, is greater than 0. {b>0)

ii. The base, b, is not equal to 1. (b\ne 1)

iii. x must be greater than 0. (x>0)

Now, if we observe all the choices given, we conclude that the third choice is correct as the base there is 1. If base is equal to 1, then it violates the definition of logarithmic functions. So, the correct choice is:

y=log_{1} x is not a logarithmic function because the base is equal to 1.
