Respuesta :
f(x)=x+4 This is the equation written in the function notation with x as the independent variable
x is independent variable means wite the function in terms of x solvng for the other variable, y
solve for y
y-x-4=0
add x+4 both sides
y=x+4
f(x)=x+4
solve for y
y-x-4=0
add x+4 both sides
y=x+4
f(x)=x+4
