Given the function f: x ⟼ 2x − 1 the value of f(-3) is:
7.
5.
-7.
-5.
Given a function ℎ, define as ℎ:(x) ⟼ 3 / (x - 1), the domain of ℎ is:
x ∈ ℜ, ≠ 0, 1, 3.
x ∈ ℜ, ≠ 0, 1.
x ∈ ℜ, ≠ 3.
x ∈ ℜ.
Given that f(x) = 3 - 2x, then, f(-1) gives:
6.
-1.
1.
The arrow diagram in the figure shows the relationship between M and N.
The domain is:
{1, 4, 9, 16}.
{1, 4, 3, 8, 16}.
{1, 4, 9, 8, 16}.
{1, 2, 3, 4}.
Given the mapping in the figure, the range set is:
{2, 5, 8}.
{2, 3, 5}
{1, 2, 5, 5, 8}
{1, 2, 3, 4}
