Which function is shown in the graph below?

The correct option is 2.

Explanation:

From the given figure it is easily noticed that the graph intersect the y-axis at y=9 , therefore the y-intercept is (0,9).

To find the equation of the curve put x=0 in each option, If we get y=9 then that option is true.

Option 1:

Option 2:

Option 3:

Option 4:

Only the equation in option 2 have the y-intercept (0,9), therefore the correct answer is option second.

step-by-step explanation:

if x = 2 you have to find x to finish the problem
