Round to the nearst tenthAnswer by jim_thompson5910(28595)   (Show Source): You can put this solution on YOUR website!In order to make a table, just plug in some n values. So I'm going to start at n=-5 Let's evaluate Start with the given function. Plug in . In other words, replace each n with -5. Evaluate to get 25. Multiply 2 and 25 to get 50 Multiply -4 and -5 to get 20 Now combine like terms -----------Now let's evaluate another value--------- Let's evaluate Start with the given function. Plug in . In other words, replace each n with -4. Evaluate to get 16. Multiply 2 and 16 to get 32 Multiply -4 and -4 to get 16 Now combine like terms -----------Now let's evaluate another value--------- Let's evaluate Start with the given function. Plug in . In other words, replace each n with -3. Evaluate to get 9. Multiply 2 and 9 to get 18 Multiply -4 and -3 to get 12 Now combine like terms -----------Now let's evaluate another value--------- Let's evaluate Start with the given function. Plug in . In other words, replace each n with -2. Evaluate to get 4. Multiply 2 and 4 to get 8 Multiply -4 and -2 to get 8 Now combine like terms -----------Now let's evaluate another value--------- Let's evaluate Start with the given function. Plug in . In other words, replace each n with -1. Evaluate to get 1. Multiply 2 and 1 to get 2 Multiply -4 and -1 to get 4 Now combine like terms -----------Now let's evaluate another value--------- Let's evaluate Start with the given function. Plug in . In other words, replace each n with 0. Evaluate to get 0. Multiply 2 and 0 to get 0 Multiply -4 and 0 to get 0 Now combine like terms -----------Now let's evaluate another value--------- Let's evaluate Start with the given function. Plug in . In other words, replace each n with 1. Evaluate to get 1. Multiply 2 and 1 to get 2 Multiply -4 and 1 to get -4 Now combine like terms -----------Now let's evaluate another value--------- Let's evaluate Start with the given function. Plug in . In other words, replace each n with 2. Evaluate to get 4. Multiply 2 and 4 to get 8 Multiply -4 and 2 to get -8 Now combine like terms -----------Now let's evaluate another value--------- Let's evaluate Start with the given function. Plug in . In other words, replace each n with 3. Evaluate to get 9. Multiply 2 and 9 to get 18 Multiply -4 and 3 to get -12 Now combine like terms -----------Now let's evaluate another value--------- Let's evaluate Start with the given function. Plug in . In other words, replace each n with 4. Evaluate to get 16. Multiply 2 and 16 to get 32 Multiply -4 and 4 to get -16 Now combine like terms -----------Now let's evaluate another value--------- Let's evaluate Start with the given function. Plug in . In other words, replace each n with 5. Evaluate to get 25. Multiply 2 and 25 to get 50 Multiply -4 and 5 to get -20 Now combine like terms Now lets make a table of the values we have calculated ``` xy -564 -442 -324 -210 -10 0-6 1-8 2-6 30 410 524 ```Now plot the points Now connect the points to graph (just replace n with x) (note: the more points you plot, the easier it is to draw the graph)
