If you don't want to plug in points to figure out the graph, you can always use a graphing calculator like desmos. https://www.desmos.com/calculator
Here are the answer choices: A.) & B.) https://snipboard.io/oqb2RX.jpg C.) & D.) https://snipboard.io/NwDB5M.jpg
Which answer choices can you eliminate? To find out where the empty circle should be- it's going to be when the function is undefined. The function is undefined when the denominator is 0. To find that value, set the denominator equal to 0 and solve. That's the x-value at which you will have an undefined value in the function. 2x + 2 = 0 x = ?
I can get rid of C.) & D.)
Correct
I think it is A.)
That is correct as the function is undefined at x = -1
