Question

What value do you get when you evaluate the composition "f of g of negative threef (x) -3x2-5 g (x) --4xf(g(-3))

Answer 1

f o g is how it's written with the -3 it means

f(g(-3))=what

so first -3 into g(x)
g(-3)=-4(-3)
g(-3)=12

sub for x in f(x)
f(12)=-3(12)^2-5
f(12)=-3(144)-5
f(12)=-432-5
f(12)=-437
