The function p(x) = x^3 is a polynomial. Here the “variable”, x, is being raised to some constant power. The function f(x)=3^x is an exponential function (the variable is the exponent).
Exponential functions tend to get very big very quickly, and though they start out smaller than polynomial functions, they will always eventually become bigger. Notice that the two functions meet at x = 2 and x = 4.
A rational number is a number that can be made by dividing 2 integers, such as 0.25 or 3/4.
An irrational number is a number that is not an imaginary number and cannot be expressed as a ratio between 2 integers. Basically, if an irrational number was written in a decimal notation, there would be an infinite amount of integers on the right side of the decimal. An example would be π (pi) or √2.
Answer:
21,000 people preferred regular toothpaste
Step-by-step explanation:
