Answer:

here you go

Step-by-step explanation:

W = (0.6) L

       P = 2  (  L + W  )

       P = 2  [  L + (0.6) L  ]

       P = 2  ( 1.6 L  )

       P = (3.2) L

Tysm for the help! <3

By using the given graph:

  • When x = -2, the value of the function is f(-2) = 1
  • When x = -0.5, the value of the function is f(-0.5) = 0.75
  • When x = 0, the value of the function is f(0) = 1.25
  • When x = 2.5, the value of the function is f(2.5) = 3
  • When x = 6, the value of the function is f(6) = 0
<h3></h3><h3>How to use the graph to find the values of the function?</h3>

Suppose that we want to find the value of the graphed function when x = a.

  • Then we first need to identify x = a in the horizontal axis.
  • Then we move upwards (or downwards) until we meet the curve of the function.
  • Now you can move horizontally towards the vertical axis, where you can read the y-value associated to the x-value.

Now we can do these steps for each of the wanted values.

  • When x = -2, the value of the function is f(-2) = 1
  • When x = -0.5, the value of the function is f(-0.5) = 0.75
  • When x = 0, the value of the function is f(0) = 1.25
  • When x = 2.5, the value of the function is f(2.5) = 3
  • When x = 6, the value of the function is f(6) = 0
