A function is an equation (a relation) which has only one y-value for every x-value. If a single x-value has more than one y-value, the equation is no longer called a function.

How do you identify a slope given in a linear equation?
To identify the slope in a linear equation, rearrange the equation into the form y = mx + b. The term m is the slope.
What is the y-coordinate of the vertex of the parabola that is given by the equation below?
We will be able to identify the answer if we have the equation. We can only check on the coordinates from the given vertex.
How do you find the zeros of any given polynomial function?
by synthetic division and quadratic equation
A function to compute the real roots of the quadratic equation?
Where the equation is ax2 + bx + c the roots are given by the solutions to : (-b +/- sqrt(b2 - 4ac))/2a
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.

When do you say that the equation is a function or not?
i may only be 10 yrs old but i can say that an equation is not an function like the graphs of quadratic functions you will only be given an equation
When you are given a graph how can you come up with a rational function equation?
You cannot, necessarily. Given a graph of the tan function, you could not.
How you identify function based from graphs and equation?
An equation is the same as a function. Identifying a functional relationship from a graph is nearly impossible unless it is trivially simple like a linear relationship.
Identify the first step to solve the given equation 2n 3 7?
5n-3
How do you identify the domain and range?
Domain is a set in which the given function is valid and range is the set of all the values the function takes
What the definition of Variable?
a variable can be defined as a quantity in an equation which explains the behaviour of the given function
How do you find the zeros of any given polynomial function?
by synthetic division and quadratic equation
How do you get the tangent line without the graph?
The answer will depend on the context. If the curve in question is a differentiable function then the gradient of the tangent is given by the derivative of the function. The gradient of the tangent at a given point can be evaluated by substituting the coordinate of the point and the equation of the tangent, though that point, is then given by the point-slope equation.
What is the function notatiom for the equation 2x 4y16?
Without an equality sign the given terms can't be considered to be a straght line equation.
Is the linear equation X equals -14 a function?
No, this is not a function. The graph would have a vertical line at x=-14. Since there are more than one y value for every given x value, the equation does not represent a function. The slope of the equation also does not exist.
