1. This is an exponential function, with base 2. Since 2 is greater than 1, the function is increasing.

For the y intercept, we have to set , and we have For the x intercept, we have to set and solve for x: And this has no solution. All we can say is that So, the x axis is an asymptote for the function, but the graph neves crosses it.

y-intercept: (0, 3)

x-intercept: There isn’t one

The graph is increasing.

Step-by-step explanation:

To find the y-intercept of a function, simply substitute 0 in for x, and calculate.

To find the x-intercept of a function, simply substitute 0 in for y, and solve for x.

To know whether the graph is increasing or decreasing, you need to look at what happens to the y-values as the value of x increases. If the values get bigger, it’s increasing and if they get smaller it’s decreasing.
