Answer:

option 2: f(x) = 4x + 4

Explanation:

Graph is positive, so with this you should already know that options: 1, 3, 4 are incorrect since those are negative.

However, let's break it down more.

To write the function for a line, you use y = mx+b

m stands for the rise/run

b stands for the y-intercept

Rise over run is 4/1, or just 4

With this we know that option 3 is not correct, yet again

Our y intercept is 4

With this we know that option 1 is not correct, yet again

This just leaves option 2 and 4 with the correct slope and y-intercept, yet as we said before this is a positive slop, so again, 4 is incorrect
