Answer: linear functions
Explanation:
Linear function shows how the value of the output varies with the input value. It shows that the output value or results depends on the input value.
E.G if f(x) = x+1 given x = (1,2,3)
When x = 1, f(x) = 1+1 =2
When x = 2, f(x) =2+2=4
When x = 3, f(x) = 3+3=6
Therefore the value of the output changes with varying input values.
This type of equation is called linear function.
