Question

Which graph represents the function y = 4?

Answer 1

Answer:

the graph that represents the function y = 4 is A.

Step-by-step explanation:

y = 4 goes across the y-axis

Answer 2

Answer:

The first one

Step-by-step explanation:

This is a constant function, i.e. the value for y doesn't depend on x. So, every x value will lead to the same y value, in this case 4.

This implies that the graph is a horizontal line, composed by all points like (x,4), where x can be any value and 4 is fixes as the y coordinate.
