Answer:
C. (0,-4)
Explanation:
The y-intercept is the point where the graph of the function crosses the y-axis.
The x-coordinate is always x = 0, and the y-coordinate is the value of the function when x = 0
Your function is ƒ(x) = -4·2ˣ.
Let x = 0. Then
f[tex](x) = -4 \cdot 2^{0} = -4\cdot1 = \mathbf{-4}[/tex]
The y-intercept is at (0,-4)
The graph below shows your function crossing the y-axis at y = -4.
