Question

The graph below shows a linear function and an exponential function. What is the minimum y-value after which the exponential function will always be greater than the linear function? y = 1 y = 3 y = 4 y = 5

Answer 1

y=4

Explanation:

yes

Answer 2

The correct option is:

y = 4

Explanation:

We can see in the graph the behavior of both the exponential function and linear function. The point (1,4) is considered to be the point where the graph of both the functions is getting separated. We can see in the graph that before point (1,4), initially the y value of exponential function is first greater than that of a linear function, then at y=2 it becomes equal, from y=2 to y=4 the value of linear function is slightly bigger than the value of exponential function. However, after point y=4, the value of exponential function corresponding to a particular value of x is always greater than the value of linear function for the same value of x
