Question

The conclusion(s) made for the given graph is/are

• A. monotonic increasing
• B. always positive
• C. always negative
• D. No conclusions

Answer 1

Answer: (A), (B)

always positive
monotonic increasing

Drawn a tangent on any point of a given curve.

It is clear that slope of the curve is never negative.

Also from point $a$ to $b$ the value of function become constant ,

Hence graph is not strictly increasing but the given function is monotonically increasing function.

Also, the given graph lies above the $X$- axis, hence it is always positive.
