Write an equation for the graph.

hoa [83]

Answer: $f(x)=-|x-3|$

Step-by-step explanation:

By definition. the parent function is the simplest form of a function.

In this case, you have that the absolute value parent function is the shown below:

$f(x)=|x|$

If you make it multiply by -1, then you obtain:

$f(x)=-|x|$

Then, the graph will open down.

The vertex is shifted 3 units to the right, therefore, this means that:

$f(x)=-|x-3|$

What is the value of v?<br> 1 / 4 (v – 7) = 2

belka [17]

1/4 (v - 7) = 2

1/4v - 1/4 (7/1) = 2

1/4v - 7/4 = 2

1/4v = 15/4

Multiply by 4/1 on both sides to get v

(4/1) 1/4v = 15/4 (4/1)

v = 60/4

v = 15
