Write an expression for this scenario
If 1 pound of blueberry cost $2.50
then b pounds = 2.50 * b
If 1 pound of apple cost $2
then a pounds = 2 * a
The required expression (y) is then calculated as
Hence, the required expression is:
Answer:
x(2x+3)
Step-by-step explanation:
2x^2+3x=x(2x+3)
Answer:
y = (x +2)/(x -3)
Step-by-step explanation:
A rational function is a function (y = ...) that has a definition that is the ratio of two polynomials.
Of the choices listed, the one attached is the rational function.
Using it's concept, the domain of the function is given as follows:
{x| –2 ≤ x <= 5}
<h3>What is the domain of a function?</h3>
The domain of a function is the set that contains all possible input values for the function, that is, the values for which the function is defined.
The function described in this problem is defined from x = -2 until x = 5 hence the domain of the function is given as follows, by the interval:
{x| –2 ≤ x <= 5}
