Preimage under a Polynomial
This calculator computes the Preimage under a Polynomial function. In others words, for a given value y0 and a Polynomial P(x), it calculates x0 such that P(x0) = y0.
How to use this calculator?
|Variable||Input a single-letter that is the polynomial variable. Examples :
polynomial = 4x+1 , then input variable = 'x'
polynomial = 9t + 5 , then input variable ='t'
|Polynomial||Are accepted :
|Examples||Polynomial = x^2-4x+1 (variable = 'x')
Polynomial = (x^2-1)(x-5)-3 (variable = 'x')
Polynomial = x^3-4/3*x^2+1 (variable = 'x')
Polynomial = 0.23*t^2-1/5*t+1/2 (variable = 't')
|x =||Input a number (integer or fraction or decimal) for which you want to calculate the image under the Polynomial. Example :
Enter x = 1/2 and the calculator will compute P(1/2), P being the polynomial you entered.
