Answer:


f(x) = -(7)/(4)|x-5|+0

Step-by-step explanation:

The function in the coordinate Plane is an absolute value function . Consider the parent function


f(x) = |x|

Recall the properties of transformation

  • f(x+a), If a<0 ⇒ It moves to right
  • a.f(x),If a<0 ⇒ It flips upsidedown
  • f(x)+a,If a>0 ⇒ It moves up & a<0 It moves down

From the inspection of the graph,It has moved to right by 5 units, Thus


f(x - 5) = |x - 5|

Apparently, It has neither shifted up or down, hence


f(x - 5) +0= |x - 5|+0

Looking at the graph, we can see that it has been reflected vertically. It tells us we have to multiply it by a negative constant


-a f(x - 5) +0= -a |x - 5| +0

take (9,7) to figure out a.

  • set x to 9 and the LHS expression to 7


-a | 9- 5| =7

Solving the equation yields:


\boxed{a = - (7)/(4) }

hence, our function is
\boxed+0

Answer:


\large{\boxed \ g(x) = -(7)/(4) }

Step-by-step explanation:

Absolute value of a graph formula:

  • y = a |x -h| + k

Identify the vertex : (h, k) = (5, 0)

Take two points : (5, 0), (9, -7)


\sf Find \ slope \ (a) : \sf \ (y_2 - y_1)/(x_2- x_1) \ = \ (-7-0)/(9-5) \ = \ -(7)/(4)

Join the variables together:
\bf g(x) = - (7)/(4) | x -5| +0
