We can find the y-intercept by plugging the value of x is zero, and from the graph, we can see the end behavior of the graph.
What is a function?
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function and y-intercepts are given in the picture.
First function:
y = 3ˣ
To find y-intercept plug x = 0
y = 1
or
y-intercept is (0, 1)
As the x increases the graph reaches the positive infinity.
Second function:
[tex]\rm y = 2(\dfrac{1}{2})^x[/tex]
Plug x = 0
y = 2
The y-intercept is (0, 2)
Graph approches zero as x increases
Third function:
[tex]\rm y = (\dfrac{1}{4})^x[/tex]
Plug x = 0
y = 1
y-intercept is (0, 1)
Graph approches zero as x increase.
For match please refer to the attched picture.
Thus, we can find the y-intercept by plugging the value of x is zero, and from the graph, we can see the end behavior of the graph.
