For which pair of functions is the vertex of k(x)7 units below the vertex of f(x)?

kvv77 [185]

Answer: Option C

$f(x) = x^2;\ k (x) = x ^ 2 -7$

Step-by-step explanation:

Whenever we have a main function f(x) and we want to transform the graph of f(x) by moving it vertically then we apply the transformation:

$k (x) = f (x) + b$

If $b> 0$ then the graph of k(x) will be the graph of f(x) displaced vertically b units down.

If $b> 0$ then the graph of k(x) will be the graph of f(x) displaced vertically b units upwards.

In this case we have

$f (x) = x ^ 2$

We know that this function has its vertex in point (0,0).

Then, to move its vertex 7 units down we apply the transformation:

$k (x) = f (x) - 7\\\\k (x) = x ^ 2 -7$ .

Then the function k(x) that will have its vertex 7 units below f(x) is

$k (x) = x ^ 2 -7$

Step one: divide both sides by -2.3 to get X by itself: X=-.2. :)

What is the transformation of f(x)=- (x + 2)2- 4

pychu [463]

Answer: x=0

Step-by-step explanation: f(x)=(x+2)x2-4

0=2x+4-4

0=2x

2x/2=0

0/2=0

x=0

What is the indicated operation of <br> 10 3/7 + 19 5/9

seraphim [82]

That's addition of mixed numbers. Convert 3/7 and 5/9 to fractions with the denominator (7)(9) = 63 (this is the LCD):

10 27/63 + 19 35/63

This comes out to 29 62/63.
