(6v^3+42v)/(2v^2+26v+84)
Kisachek [45]
Answer:
_______________________________________________
The simplied version is:
_______________________________________________
                " \frac{3v(v^2+7)}{(v^2+13v+42)}  "  ;

or; write as:  " \frac{3v(v^2+7)}{(v+7)(v+6)}  " .
_______________________________________________
Explanation:
_______________________________________________
Given:
_______________________________________________
     " \frac{6v^3 +42 v}{2v^2 +26v + 84}  " ;
_______________________________________________
     →  Factor out a "6v"\frac{6v(v^2+7)}{2(v^2+13v+42)} in the "numerator"; & factor out a "2" in the denominator;  as follows:
____________________________________
→ \frac{6v(v^2+7)}{2(v^2+13v+42)} ;
____________________________________
→  " \frac{3v(v^2+7)}{(v^2+13v+42)} " ;
______________________________________________

or; factor out the "denominator" :
______________________________________________
→ (v² + 13v + 42) =  (v+7)(v+6) ;
______________________________________________
and write as: 
______________________________________________
→  " \frac{3v(v^2+7)}{(v+7)(v+6)} " .

How would you shift the parent function y= x to graph the function y= (x-4)2 + 5?
Crank

Answer:

B. The parent function would be shifted 4 units to the right and 5 units up.

Step-by-step explanation:

Given:

Parent function:

y=x

Transformed function:

y=(x-4)+5

To find the shifts made to the parent function.

Solution:

Translation Rules:

f(x)\rightarrow f(x+c)

If c>0 the function shifts c units to the left.

If c the function shifts c units to the right.

f(x)\rightarrow f(x)+c

If c>0 the function shifts c units to the up.

If c the function shifts c units to the down.

From the functions given the translation occurring can be given as:

f(x)\rightarrow f(x-4)+5

From the rules we can see that the parent function has moved 4 units to the right and 5 units up.

The range of the function f(k) = k2 + 2k + 1 is {25, 64}. What is the function’s domain?
AveGali [126]
The domain of a function contains the x-values of the function while the range of the function contains the y-values of the function. In this case, we substitute 25 and 64 to y. Then,
25 = k2 + 2 k + 1 (k-4) * (k+6) = 0
64 = k2 + 2 k + 1 (k-7) * (k+9) = 0
hence the domain is {-9,-6, 4,7}
