How do you find the important points to graph y = 2^x + 2?

You can use the points (0,3),(1,4),(2,6). Also use the asymptote y=2.

Explanation:

In an exponential graph, one of the most important points is the y-intercept. You can find this by plugging in 0 for x:

y=2^0+2

Anything to the zeroth power is 1.

y=1+2

y-3

The y-int is (0,3).

You can also plug in 1 and 2 in x to find some other points.

y=2^1+2=4

y=2^2+2=6

You can use the points (0,3),(1,4),(2,6).

Also consider the asymptote, y=2. Check out this graph for reference:
