Practice problem
If f(x)=x∗x,f(x) = x * x,f(x)=x∗x, what does the product rule say about the derivative of f(x)f(x)f(x)?
f′(x)=x∗xf'(x) = x*xf′(x)=x∗x
f′(x)=1∗1f'(x) = 1*1f′(x)=1∗1
f′(x)=x∗1+1∗xf'(x) = x*1 + 1*xf′(x)=x∗1+1∗x
f′(x)=1∗1+x∗xf'(x) = 1*1 + x*xf′(x)=1∗1+x∗x
Type a concept, like “slope” or “photosynthesis”.
