Practice problem
What is the quadratic approximation to the function f(x)=x3f(x) = x^3f(x)=x3 at x=0x=0x=0?
f(x)≈0x2+0x+0f(x) \approx 0x^2 + 0x + 0f(x)≈0x2+0x+0
f(x)≈1x2+1x+1f(x) \approx 1x^2 + 1x + 1f(x)≈1x2+1x+1
f(x)≈2x2+2x+2f(x) \approx 2x^2 + 2x + 2f(x)≈2x2+2x+2
Type a concept, like “slope” or “photosynthesis”.
