    Answer:

    -6x^2-1

    Step-by-step explanation:

    Find value

    f(x)=-2x^2. g(x)=3x-1. Find g(f(x))

    Solution:

    f(x)=-2×2

    g(x)=3x-1

    g(f(x))=?

    f(x)=-2×2,g(x)=3x-1,gof(x)=?

    gof(x)=g(f(x))

    Solution:

    f(x)=-2×2

    g(x)=3x-1

    g(f(x))=?

    f(x)=-2×2,g(x)=3x-1,gof(x)=?

    gof(x)=g(f(x))

    =g(-2×2)

    =3⋅(-2×2)-1

    =-6×2-1

    gof(x)=-6x^2-1
