F(x) = 3x - 9 Find inverse

Step-by-step explanation:

write as an equation

interchange the variables

solve for y:

add 9 to both sides

divide each term by 3

simplify

replace y with to show the final answer of the inverse

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
