4vir4ik [10]

we know that

The vertex of the function f(x)=x^{2} is the point (0,0)

The vertex of the function f(x)=(x-h)^{2}+k is the point (4,-2)

The x-coordinate of the vertex is equal to h

the y-coordinate of the vertex is equal to k

so

the value of h is 4

the value of k is -2

the equation is

f(x)=(x-4)^{2}-2

therefore

<u>the answer is the option a</u>

4

gladu [14]

Answer:

The right response is "3(k-1)". A further solution is given below.

Step-by-step explanation:

The given expression is:

⇒ (7 -3k) - (4 - 5k) - (6 - 2k)

On solving the above expression, we get

⇒ 7-3k-4+5k-6+2k

⇒ 7-3k-10+7k

⇒ 3k-3

On taking "3" as common, we get

⇒ 3(k -1 )
