What type of function is f(x) = 2x + 3

It is a positive linear function.

Step-by-step explanation:

If you were to graph the equation, it would show up as a diagonal line raising from the negative end of the graph to the positive end. This is because it contains a positive number being multiplied by x, making the function positive, and it contains no exponent, making it linear.

sum= when you add is how much the whole amount is

distance= when you use angles and it means how far it goes

step-by-step explanation:

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.
