Suppose a = {x |x ≤ −2, x ≥ 3} and b = {x | −1 ≤ x < 5}. which statement is true?
a. a ∪ b is all real numbers
b. a ∩ b = ∅
c. a' = {x | −2 ≤ x ≤ 3}
d. b ⊆ {x | x ≤ 5}

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
