Answer: y=-(x-1)^{2} +3

Step-by-step explanation:

Vertex form of the equation is

y = a(x – h)2 + k, where (h, k) is the vertex.

your vertex is at (1,3)

the equation would bey=a(x-1)^{2}  +3

Use the through point to find a

-1=a(3-1)^{2} +3\\-1=4a+3\\-4=4a\\-1=a

Final Equation would be

y=-(x-1)^{2} +3

What is f left parenthesis 4 right parenthesisf(4) for the function f left parenthesis x right parenthesis equals 2 x plus 6f(x)
I am Lyosha [343]

Answer:

f(4)=14

Step-by-step explanation:

Given function is f(x)=2x+6

We need to find the value of f(4)

For any function f(x) if we want to find the value of f(a), we need to plug x=a in the function.

So, we will plug x=4 in the function f(x)=2x+6

f(4)=2(4)+6\\f(4)=8+6\\f(4)=14

So, the value of f(4) in the function f(x)=2x+6 is 14
