What is the yintercept of the function f(x) = -4x2

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

The y-intercept is at (0,-4)

The graph below shows your function crossing the y-axis at y = -4.
