Question

The graph of a rational function, f, is shown in the figure. Use the graph to find f(-2)

Answer 1

When we plug a value into a function, we are looking for the y-value. To find f(-2), we are looking for the point (-2, y). So, we need to find the y-value for this function where the x-value is -2.

f(-2) = -4

Hope this helps! :)
