Well, for 20 you just add them, to get 4x^2-x+3. For 21, you do a substraction: 2x^2+7x-11. It'd take him quite some time (does this one even have zeros? :)) )

Given the function f(x)=3^x, find the value of f^-1(27)
Shalnov [3]

This is asking you to solve the equation ...

... 27 = 3^x

You can use logarithms to find

... log(27) = x·log(3)

... log(27)/log(3) = x = 1.43136376.../0.47712125...

... x = 3

Or, you can use your knowledge of small cubes and match exponents.

... 3^3 = 3^x

... 3 = x
