dy/dx represents the:
The side of a square is increasing at 2 cm/s. The rate of increase of area when side = 4 cm is:
If A = πr², then dA/dt equals:
If V = (4/3)πr³ (sphere), then dV/dr equals:
Sample Questions
The approximate change in y = f(x) for a small change Δx in x is:
Show answer
f'(x)·Δx
Δy ≈ dy = f'(x)·Δx. The differential dy is the approximate change in y.
For f(x) = √x and x = 25, Δx = 0.5, the approximate value of √25.5 is:
Show answer
5.05
f(x)=√x, f'(x)=1/(2√x)=0.1 at x=25. f(25.5)≈5+0.1×0.5=5+0.05=5.05.
A function f is strictly increasing on interval I if:
Show answer
x₁ < x₂ ⟹ f(x₁) < f(x₂) for all x₁,x₂ ∈ I
Strictly increasing means a larger x always gives a strictly larger f(x).
If f'(x) < 0 for all x ∈ (a,b), then f is:
Show answer
Strictly decreasing on (a,b)
f'(x) < 0 means the function is falling — it is strictly decreasing.
