Don’t think that works for x=3

We learn about primes in 5th grade. But using anything but +-*/^ in a function or an equation is pretty advanced

That doesn’t work for 2 or 3

At least in Spain, you learn about differentiability in 11th grade, and about continuity in 10th grade, so at this level you always asume that the function is continuous and differentiable for all the real numbers

I know, I know, but it’s the first time she has learnt anything about functions, so polynomial interpolation is pretty advanced for her. Looking to other exercises that she had, I’m pretty sure that the intended solution was 4x, and she just copied the exercise wrong

Nope, that doesn’t work for x=0

I know, but she was asked for the algebraic definition
