Question

Find each value if f(x)= 3x-5 and g(x)=x^2=x

1.) f(-3)
2.) f(2/3)
3.) g(5n)

Answer 1

f(-3) = (3(-3)-5) = -14
f(2/3) = (2-5) = -3
g(5n) = ?

You wrote g(x) = x^2 = x <----- I'm positive that isn't correct as written

Answer 2

Do you see your mistake?

Answer 3

repost g(x) correctly if possible

Answer 4

Sometimes it's hard to notice your mistake I suppose

Answer 5

yes but for some reason it has g(5n) and thank~you because I'm not good at math

Answer 6

Yeah, I figured you won't notice your own mistake: I'll give you some choices... Is it:

g(x) = x^2 = x
g(x) = x^2 + x
g(x) = x^2 - x

Which one is it?

Answer 7

neither I gt the answer thanks for helping me

Answer 8

I was referring to the original function you posted. It has to be at least one of those because you posted it. Except the one you posted is definitely not the correct g(x) because x^2 does not equal x unless x equals zero or one.

Answer 9

g(5n) = ?
25n^-5n this is the answer

Answer 10

Okay, so I believe your original g(x) = x^2 - x

which means....

g(5n) = (5n)^2 - 5n = 25n^2 - 5n

Answer 11

yes your correct
