when a graph is a smooth curve it means that there is not a definite law connecting the two quantities which are plotted true or false​

If you shift the linear parent function, f(x)=x, up 13 units, what is the equation of the new function?

Solve by any method (graphing, substitution or linear combination)y = x - 82x + 3y = 1a) (2, -6)b) (5, -3)c) (4, -4)d) (0, -8)i figured it out. the answer is (5, -3)

The graph of a function f(x)=(x+2)(x-4). which describes all of the values for which the graph is negative and increasing? all real values of x where x< -2 all real values of x where -2
