SUMMARY

The discussion focuses on solving a mathematical problem involving a graph with 5 horizontal and 5 vertical lines, where each line represents a change of 2 in both the x and y directions. To find the value of the function f(-4), the process involves moving left from the origin by 4 units (2 lines) and then determining the corresponding y-value by counting the vertical lines to the graph. The final function value is obtained by multiplying the number of lines counted by 2.

What help do you need? You can see that, since there are 5 horizontal and 5 vertical lines between the origin and "10" that each line represents a change of 2 in x and y. To find f(-4), start at the origin and go left(because it is negative) 2 lines (2 times 2= 4). Now go straight up to the graph of the function. How many lines is that? Don't forget to multiply the number of lines by 2 to get the function value.
 
Thank you
you given me Answer Key
