Sagot :
y = 25 + 5x
let x = 1
then
y = 25 + 5(1) = 30
let x = 3
then
y = 25 + 5(3) = 40
let x = 1
then
y = 25 + 5(1) = 30
let x = 3
then
y = 25 + 5(3) = 40
linear function is under polynomial function,
its characteristic is slanting line when you draw a graph
example
f(x)=2x+5
the domain is {x|x is a real number}
the range is {y|y is arel number}
thats it....
