Question

Let f(x)=2xsquared+1 and g(x)=x-1/x
Answer choices:
-6

33/32

32/33

-2

Answer 1

FIND (g o f)(-4)

Answer 2

\[ g(x) = \frac{x-1}{x} \]
?

Answer 3

yea

Answer 4

(g o f)(-4) = g( f(-4) )

f(-4) = 2(-4)^2 + 1
= 2(16) + 1
= 32 + 1
= 33 ( insert back into g(x) )

g(33) = (33 - 1)/33
= 32/33

Answer 5

yea same
