If f(x)=x3f(x) = x^{3}, what is f′(2)f'(2)?

f′(x)=3x2f'(x) = 3x^{2}, so f′(2)=3⋅22=12f'(2) = 3 \cdot 2^{2} = 12.

Find ddx[x2sin⁡x]\dfrac{d}{dx}\left[x^2 \sin x\right].

Product rule: (fg)′=f′g+fg′=2xsin⁡x+x2cos⁡x(fg)' = f'g + fg' = 2x\sin x + x^2\cos x.

If f(x)=2x2f(x) = 2x^{2}, what is f′(3)f'(3)?

f′(x)=4x1f'(x) = 4x^{1}, so f′(3)=4⋅31=12f'(3) = 4 \cdot 3^{1} = 12.

Mid-gameeasy

If f(x)=x2f(x) = x^{2}, what is f′(5)f'(5)?

f′(x)=2x1f'(x) = 2x^{1}, so f′(5)=2⋅51=10f'(5) = 2 \cdot 5^{1} = 10.

Mid-gameeasy

If f(x)=x4f(x) = x^{4}, what is f′(1)f'(1)?

f′(x)=4x3f'(x) = 4x^{3}, so f′(1)=4⋅13=4f'(1) = 4 \cdot 1^{3} = 4.

Mid-gameeasy

If f(x)=3x2f(x) = 3x^{2}, what is f′(2)f'(2)?

f′(x)=6x1f'(x) = 6x^{1}, so f′(2)=6⋅21=12f'(2) = 6 \cdot 2^{1} = 12.

Mid-gameeasy

If f(x)=x3f(x) = x^{3}, what is f′(1)f'(1)?

f′(x)=3x2f'(x) = 3x^{2}, so f′(1)=3⋅12=3f'(1) = 3 \cdot 1^{2} = 3.

Buzzer beatereasy

If f(x)=2x3f(x) = 2x^{3}, what is f′(1)f'(1)?

f′(x)=6x2f'(x) = 6x^{2}, so f′(1)=6⋅12=6f'(1) = 6 \cdot 1^{2} = 6.
