Sagot :
1. in mathematics, the term linear function refers to two distinct but related notions In calculus and related areas, a linear function is a function whose graph is a straight line, that is, a polynomial function of degree zero or one.
2. The graph of a linear function is a straight line. Graphically, where the line crosses the x -axis, is called a zero, or root. Algebra
ically, a zero is an x value at which the function of x is equal to 0 . Linear functions can have none, one, or infinitely many zeros.
3.domain: The set of all points over which a function is defined. range The set of values the function takes on as output
Answer:
1. A function that represents a straight line on the coordinate plane.
2. It is a straight line.
3. The domain of a function is the set of values that we are allowed to plug into our function.
4. I learned the domain and range. I can know a graph of a linear function.
