यदि प्रत्येक बिंदु पर f′(x) > 0 एक अंतराल में है तो फलन को निरंतर वर्धमान फलन कहा जाता है।
गणना:
दिया गया है कि , f(x) = 2x2 - 3x
अवकलन करने पर, हमें निम्न प्राप्त होता है
f'(x) = 4x - 3
f(x) निरंतर वर्धमान फलन है
∴ f'(x) > 0
⇒ 4x - 3 > 0
⇒ 4x > 3
⇒ x > \(\rm\frac{3}{4}\)
∴ x ∈ (\(\rm\frac{3}{4}\), ∞)
