The value is an input of the function? 4
Explanation:
The graph represents a functional relationship. On a coordinate plane, a straight line with a negative slope begins at point (1, 3), crosses the x-axis at (4, 0), and exits the plane at (18, negative 14). Which value is an input of the function?
A functional relation definition is a binary relation R⊂A×B between sets A and B, such as (a,b)∈R and (a,c)∈R imply b=c.
By determining whether a relation is a function involves making sure that for every input there is only one output. In order for a relation that called function, each X value must have one Y value whereas X has to have one Y value. X is the independent variable or input value, whereas Y is the dependent variable or output value
According to the graph attached, the linear function domain is equal to the interval [1,∞). All real numbers according to the graph is greater than or equal to 1. Whereas the linear function range is equal to the interval (-∞,3]. All real numbers less than or equal to 3, the value of 4 is an input of the function
