Select the function that matches the graph.

y = 3x + 1 is the required function.

Step-by-step explanation:

We are given with a graph

We have to find function for the graph,

From graph, Point ( 0 , 1 ) lies on line.

Function 1),

y = 3x - 1

LHS = y = 1

RHS = 3x - 1 = 3×0 - 1 = -1

LHS ≠ RHS

Thus, this is not function of graph.

Function 2),

y = 3x + 1

LHS = y = 1

RHS = 3x + 1 = 3×0 + 1 = 1

LHS = RHS

Thus, this is function of the graph.

Function 3),

y = 3x

LHS = y = 1

RHS = 3x = 3×0 = 0

LHS ≠ RHS

Thus, this is not function of graph.

Function 4),

y = 3x² + 1

This function is not linear

So, it can not be a straight line.

Thus, It is not function of graph.

Therefore, y = 3x + 1 is the required function.

not enough information

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.
