    Answer:

    -5

    Step-by-step explanation

    Given the function  f(x)=-4x^2+2x-5, the y intercept occurs at x = 0

    Substitute x = 0 into the function and find y as shown;

    f(x)=-4x^2+2x-5

    f(0)=-(0)^2+2(0)-5

    f(0)=0-5

    f(0) = -5

    The coordinate point is (0, -5)

    Hence the value of the y coordinated is -5
