Classwork/Homework:
Which of the following equations represent exponential functions
A. f(x) = 2x3 + 1
B. f(x) = -4*
C. f(x) = 1+
D. f(x) = 3(2)*

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.

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is
