Select the function that matches the graph.y = 3xy = 3x2 + 1y = 3x - 1y = 3x + 1

Answer:the first one goes through (0,0) ||||||| the second is an exponential function so it goes through (0,1) and in a u shape going up ||||||| The third goes through (0,-1) ||||||||| The fourth goes through (0,1)Step-by-step explanation:these are identifiein traits so you can find wich one the graph corresponds to since u never gave us a graph.
