Sketch the graph of f(x) = sqrtx. Also, find the domain and range.
Sketch the graph of $f(x) = \sqrt{x}$. Also, find the domain and range. [5]
The function f(x) = √x is defined only for non-negative real numbers (since we cannot take the square root of negative numbers in the real number system). Domain: [0, ∞) or {x ∈ ℝ x ≥ 0} Since √x produces only non-negative outputs: - When x = 0, f(0) = 0 - As x increases, √x increases without bou...
