Question
p(x) = √𝑥3 + 1 is not a polynomial. Give reason
Solution
To determine if the function p(x) = √𝑥^3 + 1 is a polynomial, we need to consider the definition of a polynomial.
A polynomial is a mathematical expression consisting of variables, coefficients, and non-negative integer exponents, combined using addition, subtraction, and multiplication operations. The exponents must be whole numbers, and the variables cannot appear in the denominator or inside any radical expressions.
In the given function p(x) = √𝑥^3 + 1, we have a square root (√) symbol, which indicates a radical expression. The exponent in the radical expression is 3, which is not a whole number. Therefore, the given function does not meet the criteria for a polynomial.
Hence, we can conclude that p(x) = √𝑥^3 + 1 is not a polynomial.
