The question says given the function f(x)find the following: a graph is then shown with a) f(-1) b) f(3) c) find x when f(x) = -2 I have no idea where to start. I can't show you the graph here but there is a line with a starting point and ending point
To find the values of f(-1), f(3), and x when f(x) = -2, you would need to use the graph provided.
1. To find f(-1): Look for the point on the graph corresponding to x = -1. The value of f(-1) is the y-coordinate of this point. If the graph is displaying a straight line, you can simply read off the value. For example, if the point is (-1, 2), then f(-1) = 2.
2. To find f(3): Similarly, locate the point on the graph where x = 3. The value of f(3) is the y-coordinate of this point. Again, if the graph is a straight line, you can directly read off the value from the graph.
3. To find x when f(x) = -2: Look for the value of x on the graph where the y-coordinate is -2. Follow the line on the graph until you intersect with the y = -2 line. Then, identify the corresponding x-coordinate at that point of intersection. This value of x will be the x when f(x) = -2.
While I cannot see the specific graph you are referring to, these general instructions should help you find the desired values on a line graph.
