What is the range of f(x)? { f(x)| –∞ < f(x) < ∞} { f(x)| –∞ < f(x) ≤ 4} { f(x)| 4 < f(x) < ∞} { f(x)| 0 ≤ f(x) < ∞}

{ f(x)| –∞ < f(x) ≤ 4}

Step-by-step explanation:

The range of f(x) is whatever number f(x) can be. From the graph, f(x)=4 for x<0 and then f(x) decreases from there. The only answer that makes sense is { f(x)| –∞ < f(x) ≤ 4}.

5/6

step-by-step explanation:

if i remember correctly with perpendicular stuff you just take away the negative

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.
