Suppose that the equation px -5x2 600x 100 where x represents the number of items sold describes the profit function for a certain business How many items should be sold to maximize the pro?
Amazingemory
P'(x) = -10x + 600 To maximise equation, let P'(x) = 0 Therefore, 0 = -10x + 600 10x = 600 x = 60 Therefore, 60 items must be sold in order to maximise profits. I hope this has helped! ^.^

How do you determine if a relation represents a function?
If the function is a straight line equation that passes through the graph once, then that's a function, anything on a graph is a relation!
What is it called when an equation describes a function?
I don't think there is a special name for that. Note that not all functions can be described by a single equation - at least, not in a natural way. For example, a function may be described by parts.
What is the difference between a function and an equation?
A function describes a relation between several variables. For example the function f(x)=x2 describes a mapping from the variable x to a value that is the square of x. That is, for every real number we put as x, we will get a value for f(x). A function is defined for some domain and gets values from some range. An equation takes two terms and says they are equal. Usually both terms are functions of the same variable(s). For example, to build the equation x2 = x+2, we will use f(x) = x2, g(x) = x+2 and say that f(x)=g(x). Solving an equation means finding the set of values of the equation's variables which satisfy the equation. This set of values has to be part of the domains of the functions in both terms of the equation.
What is the difference between a linear function and a quadratic equation?
A linear equation describes a line like 2x+1=y. If you were to graph that equation, then it would give you a line. A quadratic equation is like x^2+2x+1=y. Graphing this equation would give you a U shaped graph called a parabola.
Is a linear equation the same as a function?
No a linear equation are not the same as a linear function. The linear function is written as Ax+By=C. The linear equation is f{x}=m+b.
An equation that describes a function?
a function rule
What equation describes the cosine function for a right triangle?
mathematical equation
What statement describes the equation y equals 12x?
A function.
What best describes a linear function?
A linear function is a function, or equation, that when graphed, will form a straight line.
what is wave function?
The official definition for the word wave function is "a function that satisfies a wave equation and describes the properties of a wave."
Does the equation y equals 2x plus 1 represent a function?
The [ 2x + 1 ] represents a function of 'y' .
How do you determine if a relation represents a function?
If the function is a straight line equation that passes through the graph once, then that's a function, anything on a graph is a relation!
Which equation describes the tangent function for a right triangle?
tan (0) = opposite/adjacent
Which equation describes the sine function for a right triangle?
sin(0) = opposite/hypotenuse
What are the uses of derivatives?
A derivative of a function represents that equation's slope at any given point on its graph.
What are uses of derivatives?
A derivative of a function represents that equation's slope at any given point on its graph.
What represents the point on the vertical axis and also describes the initial amount of a function?
It is the y-intercept.
