Draw a graph of the function [[$ f(x) = 2x - 7 $]] when [[$ -2 ≤ x ≤ 5 $]].

Take a picture of your solution and return it to the submission folder.

Use the graph to determine

a) [[$ f(0) = $]] .

b) [[$ f(4) = $]] .

c) at which value of [[$ x $]] the value of the function is [[$ 0 $]]?

Answer: The function gets the value [[$ 0 $]] when [[$ x = $]] .
