(a). define set a as a = {x ∈ r | x > 4, x not in q}. find a formula for an injective function g from n into a. prove that your function is injective. (b). define set b as the set of all perfect squares having three or more digits. find a formula for a bijective function g from n to b. prove that your function is bijective.

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
