Can someone show me how to figure this problem out:
Find the x intercept of the function, f(x)=-3x-9
The function crosses the x axis when x is equal to 0. That would be point (0,y)
So set your function to 0 and solve.
0=3x-9
9=3x
3=x
That means when you set x to 0 y will equal 3.
The y intercept is 0,3
