Verticle line test man. If it intersects two points it is its not a function. if it hits one point it is a function. and im currently looking up to see how it is a equation...
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!
you will know if it is Function because if you see unlike abscissa in an equation or ordered pair, and you will determine if it is a mere relation because the the equation or ordered pairs has the same abscissa. example of function: {(-1.5) (0,5) (1,5) (2,5)} you will see all the ordinates are the same but the abscissa are obviously unlike example of mere relation: {(3,2) (3,3) (3,4) (3,5)} you will see that the ordinates aren't the same but the abscissa are obviously the same. Try to graph it.!
True.
true
The graph of a quadratic relation is a parobolic.
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!
In general you cannot. Any set of ordered pairs can be a graph, a table, a diagram or relation. Any set of ordered pairs that is one-to-one or many-to-one can be an equation, function.
Does the graph above show a relation, a function, both a relation and a function, or neither a relation nor a function?
MATH 1003?
A relation is a function when an x value only has one y value associated with it. An easy way to tell this is to graph the relation, then draw a vertical line through it. If, at any point, it touches the graph twice, the relation isn't a function.
A linear function is a function whose graph is a straight line.
A function is an equation that is a straight line when plotted on a graph.
If a vertical line intersects the graph at more than one point then it is not a function.
You cannot, necessarily. Given a graph of the tan function, you could not.

If a graph is a function, it will always have y=... or x=... (or anoher letter equals an equation) for example y= 3x-12 is a function
True.
