Practice problem
Determine the interval(s) on which the function is increasing and decreasing.
f(x)=−3x−1f(x)=-3\sqrt{x}-1f(x)=−3x−1
Increasing on x≤0x\leq0x≤0
Increasing on x≥0x\geq0x≥0
Increasing on (−∞,∞)(-\infty,\infty)(−∞,∞)
Decreasing on x≤0x\leq0x≤0
Decreasing on x≥0x\geq0x≥0
Decreasing on (−∞,∞)(-\infty,\infty)(−∞,∞)
Type a concept, like “slope” or “photosynthesis”.
