All are correct
Explanation:since in none of the answers share the same the same X value and since the graph passes the vertical line test it is a function
it is impossible to combine like terms. In order to combine like terms you must have like x+x you cant have like 1+x
Between 4:30 and 6:15 it is 1 hour and 45 minutes
You have not provided a function, however, normally when the instructions say to use graphs, you just need to graph it in your calculator and then take a look at it to see what the limit will be at the requested x value. Remember to write your asymptote as a linear equation once you identify it from the graph.
