70

168

−1

Answer 1

Put 5 in place of x in g(x).
Can u plz tell me vat u get @Solmyr?

Answer 2

g(5) = 25-1
g(5) = 24

Answer 3

ya perfect:)

Answer 4

Nw to find f(g(5))
put g(5) in place of x in f(x).
Can u plz tell me vat u get?

Answer 5

f[g(5)] = 3(5) - 2
f[g(5)] = 15 - 2
f[g(5)] = 13

Answer 6

@ajprincess

Answer 7

hmm no.
u hav to put 24 for x nt 5.

Answer 8

so
f[g(24)] = 13

Answer 9

oops no
f(g(5))=3(24)-2

Answer 10

oh
f[g(5)] = 3(24) - 2
f[g(5)] = 72 - 2
f[g(5)] = 70

Answer 11

ya perfect:)
