The function f f\,f is defined by f(x)=∣x∣+5f(x) = |x| + 5f(x)=∣x∣+5 for x∈Rx \in \mathbb{R}x∈R.
Using set notation, state the range of fff.
Circle your answer.
{f(x):f(x)≥0}\{f(x) : f(x) \geq 0\}{f(x):f(x)≥0}
{f(x):f(x)≥5}\{f(x) : f(x) \geq 5\}{f(x):f(x)≥5}
{f(x):f(x)>5}\{f(x) : f(x) > 5\}{f(x):f(x)>5}
{f(x):f(x)≤5}\{f(x) : f(x) \leq 5\}{f(x):f(x)≤5}
