Answer 1

-6x^2-1

Explanation:

Find value

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

Solution:

f(x)=-2x2

g(x)=3x-1

g(f(x))=?

f(x)=-2x2,g(x)=3x-1,gof(x)=?

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

Solution:

f(x)=-2x2

g(x)=3x-1

g(f(x))=?

f(x)=-2x2,g(x)=3x-1,gof(x)=?

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

=g(-2x2)

=3⋅(-2x2)-1

=-6x2-1

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