Answer 1

It's not C, i've tried that.

Answer 2

Answer 3

did you figure out what f(3) and g(3) is ?

Answer 4

Nope, i have no ide how to do this.

Answer 5

f(x) = 3^x
f(3) means "replace the x with 3"
can you do that ? what expression do you get ?

Answer 6

f(3)=3^x??

Answer 7

Sorry, i'm really bad at this e.e

Answer 8

I still see an x in your answer. replace it with 3
try again

Answer 9

f(3)=3^3???

Answer 10

exactly

now we do arithmetic
any idea what \( 3^3\) is ?

Answer 11

27 right?

Answer 12

I know it's not C, i have tried that and it was wrong e.e

Answer 13

yes 3*3*3= 27
so f(3) is 27

now we need to figure out g(3)
same idea:
g(x)= 7x+6
which means 7*x + 6 (we usually leave out the multiply sign, but when we "plop in" a number, we better put the multiply sign in)
now write down g(3): replace the x with 3
what do you get ?

Answer 14

g(3)=7 3+6

Answer 15

I don't know if that's right.

Answer 16

yes, but put in the * (for multiply) otherwise it looks like 73 instead of 7*3

g(3)= 7*3 + 6
now simplify to get 21+6 or 27

Answer 17

ok.. sooooo

Answer 18

I don't know how to approach this.

Answer 19

so it looks like they both have the same value.

But I bet f(4) will be much bigger than g(4)
because 3*3*3*3 is 3*27 = 81
and g(4) is 7*4+6

Answer 20

Ok, so Month 4?

Answer 21

yes

Answer 22

ok, thanks :)

Answer 23

It was right :D
