The given three functions all have the same y-intercept at (0,-3).
We have given that,
f(x) = −6x − 3
g(x) is the graph
h(x) = h(x) = 2 cos(x + π) − 1
What is the coordinate?
A coordinate plane is a two-dimensional plane formed by the intersection of a vertical line called y-axis and a horizontal line called x-axis.
all you have to do is substitute 0 for x and you can also sub y for the function notation
So the first is y=-6x-3
When x=0 then all you have left is y=-3 so the point is (0,-3)
The second function is shown on the graph and the y-intercept (where x=0) is at -3, so the point for that is (0,-3)
And the third function has x=0, So you get[tex]y=2cos(\pi )-1.[/tex]The [tex]cos(\pi )=-1,[/tex]
So that gives
[tex]y=2(-1)-1\\y=-2-1\\ y=-3[/tex]
then and the point is (0,-3)
Therefore they all have the same y-intercept at (0,-3).
