Question

How do you graph the function f(x)=x3−2 and its inverse?

Answer 1

Answer:

Hope it helps

Step-by-step explanation:

You're gonna try numbers.

for x = 0 => f(0) = 0 - 2 = -2

for x = 1 => f(1) = 1^3 -2 = 1 - 2 = -1

for x = 2 => f(2) = 2^3 - 2 = 8 -2 = 6

2 numbers are enough but more give you a better idea of the graph.

Then you go to the axis and for every x match with a y. So for x = 0, the y = -2. for x = 1, the y is -1. for x =2, the y= 6. So you draw 2 parallel lines, one parallel to x from the y point (if y=-2 you draw it from -2) and one parallel to y from the x point (if x = 1 you draw it from 1). and when these lines connect you put a dot. And then you connect the dot.

But since it is in ^3 you can't draw straight lines. They have to be curved. The graph is something like the one in the picture
