I'm assuming you want to graph right?



In order to graph , we need to plot some points. To do that, we need to plug in some x values to get some y values


So let's find the first point:



Start with the given function


Plug in


Raise -1 to the 2nd power to get 1


Multiply -3 and 1 to get -3


Multiply 1 and -1 to get -1


Add -3 and -1 to get -4


Subtract 5 from -4 to get -9


So when , we have


So our 1st point is (-1,-9)


-------------- Let's find another point --------------


Start with the given function


Plug in


Raise 0 to the 2nd power to get 0


Multiply -3 and 0 to get 0


Multiply 1 and 0 to get 0


Add 0 and 0 to get 0


Subtract 5 from 0 to get -5


So when , we have


So our 2nd point is (0,-5)


-------------- Let's find another point --------------


Start with the given function


Plug in


Raise 1 to the 2nd power to get 1


Multiply -3 and 1 to get -3


Multiply 1 and 1 to get 1


Add -3 and 1 to get -2


Subtract 5 from -2 to get -7


So when , we have


So our 3rd point is (1,-7)


Now lets make a table of the values we have calculated
xy
-1-9
0-5
1-7
Now plot the points



Now connect the points to graph (note: the more points you plot, the easier it is to draw the graph)
