Practice problem
Determine the interval(s) on which the function is increasing and decreasing.
f(x)=−x+4f(x)=\sqrt{-x+4}f(x)=−x+4
Increasing on x≤4x\leq4x≤4
Increasing on x≥4x\geq4x≥4
Increasing on (−∞,∞)(-\infty,\infty)(−∞,∞)
Decreasing on x≤4x\leq4x≤4
Decreasing on x≥4x\geq4x≥4
Decreasing on (−∞,∞)(-\infty,\infty)(−∞,∞)
Type a concept, like “slope” or “photosynthesis”.
