Which set of ordered pairs could be generated by an exponential function?A.(0,0),(1,1),(2,8),(3,27)B.(0,1),(1,2),(2,5),(3,10)C.(

Travka [436]

Answer:

Option D

Step-by-step explanation:

Let an exponential function

$f(x)=ab^x$

Where a=Constant $\neq 0$

$b\neq 0$

We know that

$b^0=1$

Therefore,

Point (0,0) can not be obtained by exponential function.

Hence,option A and C are incorrect.

Substitute (0,1)

$1=a$

$f(x)=b^x$

Substitute (1,2)

$2=b^1$

$\implies b^2=4\neq 5$

Hence, option B is incorrect.

D.(0,1),(1,3),(2,9),(3,27)

$f(1)=b=3$

$b^2=(3)^2=9$

$b^3=3^3=27$

Hence, option D is correct.

According to the Fundamental Theorem of Algebra, which polynomial function has exactly 11 roots?

Reika [66]

B would be the right one

F(x) = (x+2)^3 = the highest power for this type turn out will be x^3
the other part is (x^2 - 7x + 3)^4, the highest power for this part will be x^8
since (x+2)^3(x^2-7x +3)^4 = the highest power of first part x^3 second part x^8
x^3 * x^8 = x^11 that result in 11 roots
This type of math, you don't need to configure the whole problem, you just need to know the basic rules of power of a number. For example, (x^2)^3, then 2*3 = 6 make x^6.
or x^2 * x^3 = x^2 + 3 = x^5.
