Answer:
Set x = +1 and -1 and calculate again (1,-1) (-1,9)
Set x = +2 and -2 and calculate again (2,-24) (-2,32)
Step-by-step explanation:
Start by calling f(x) y
Make a table for x vs y
Starting at x = 0 calculate y using the equation in this case y=4 point (0,4)
Set x = +1 and -1 and calculate again (1,-1) (-1,9)
Set x = +2 and -2 and calculate again (2,-24) (-2,32)
At this point you may realize that the function is going to accelerate away in both directions as you increment x slightly more up and down. But the area between -1 and 1 seems more interesting so investigate it more by looking at the half points
For the range of interest divide the range by half 1 to -1 mid point 0, we have already don that, so half again
x= +1/2 and -1/2
X= +1/4 +3/4 and -1/4 -3/4
Eliminate parts of the curve that are featureless and concentrate on the rest until you have a good idea of the shape. Then plot it
