Let f be defined as shown.
What is f^-1(-2)?

Step-by-step explanation:

hello

in the output check where you can see -2

and then follow the arrow to find the corresponding item in input which is -2

hope this helps

you would need to know all the numbers that are on there

step-by-step explanation:

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
