As <em>x</em> approaches -1 from the left, the graph of <em>f(x)</em> leads you to the point (-1, 3), so the limit from the left is 3.
As <em>x</em> approaches -1 from the right, the graph leads to the point (-1, -3), so the limit from the right is -3.
The one-sided limits do not match, so the two-sided limit does not exist.
But <em>f(x)</em> is still defined at <em>x</em> = -1; this is indicated by the point (-1, -1). So <em>f</em> (-1) = -1.
First, you want to find out how many kilometers are in one mile. So you take the information you are given and divide 16 km by 10 and you get 1.6 km/1mi. Now, you know that the distance between the two towns is 45 miles, so simply multiply 1.6 by 45 to get 67.5 km in 45 mi.
