You can tell if an equation is a function if for any x value that you put into the function, you get only one y value. The equation you asked about is the equation of a line. It is a function.
Equation of the circle: (x-3)^2 +( y+13)^2 = 169
a function rule
The set of all values of x, for which the equation is true is the domain of the function defined by that equation.
A logarithmic equation would be any equation that includes the log function.
Restate question: What is an example of a non-function? The equation of a circle is x2 + y2 = r2. Since a function can only be intersected once by a vertical line, the circle is not a function (almost any vertical line through the circle will cut it twice). If you solve the equation for y, you must write: y = +/- sqrt(r2-x2), so for each value of x there are TWO values of y.
The period of a circle is not typically a relevant term used to describe circles. However, if you mean the period of a function that describes points along the circumference of a circle, it would depend on the specific function being used.
You can certainly express the radius as a function of its area, yes. If the area is known, you can solve the formula for the area of the circle to uniquely get the radius. (The quadratic equation has two solutions; you will of course choose the positive solution for the radius.)
No, a circle graph is never a function.
a) A circle is not the graph of a function. b) A circle is not linear.
No. By definition, a function has a single unique value for every value passed into it. The equation given here describes a circle, which can not be rearranged to meet this condition.
The general equation of a circle is given by the formula(x - h)2 + (x - k)2 = r2, where (h, k) is the center of the circle, and r its radius.Since the center of the circle is (0, 0), the equation reduces tox2 + y2 = r2So that the equation of our circle is x2 + y2 = 36.
You can tell if an equation is a function if for any x value that you put into the function, you get only one y value. The equation you asked about is the equation of a line. It is a function.
The radius of a circle = the diameter of the circle divided by 2
The radius of the circle decreases when you make the circle smaller.
The equation of the circle is: x^2 + y^2 = 81
The shape of a circle IS capable of being described by an algebraic function. so no
