# The range of which function is (2, ∞)?

y = 2x, y = 2(5x), y = 5x + 2, y = 5x + 2

**Solution:**

The domain of the expression is all real numbers except where the expression is undefined

**Step 1:**

The function has y = 2x has no restrictions for its domain, since it's defined for all x ∈ R. The domain of the function is (-∞,∞) and the range also is (-∞,∞).

**Step 2:**

The function y = 2(5x) is defined for all x ∈ R. The domain of the function is (-∞,∞) and the range also is (-∞,∞).

**Step 3:**

The function y = 5x + 2 is defined for all all x ∈ R. The domain of the function is (-∞,∞) and the range also is (-∞,∞).

## The range of which function is (2, ∞)?

**Summary:**

None of the functions has range (2, ∞).
