Abelita and Franco had great service during the meal. They would like to tip the server 20 percent. Which of these expressions would find the total bill, including tax and gratuity? Check all that apply. (0.2)(11.72)
11.72 – [(0.2)(11.72)]
11.72 + [(0.2)(11.72)]
(1.2)(11.72)

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.

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph

answer: the is put the 450
