Question

Please help! :))

Which of these is another way to write the function g(x)=3x?


g(x)=3(9x−2)

g(x)=9(3x−2)

g(x)=3(9x+2)

g(x)=9(3x+2)

Answer 1

g(x)=9(3^x-2)

Explanation:

I just took the exact quiz and got it right. You need to make sure you specify that the "x" minus or plus whatever is a exponent.

Answer 2

Check below

Explanation:

Hi,

We're dealing with linear functions.
`f(x)=mx+b`

We have here the first function.

`g(x)=3x`

That's a linear function, with slope, and no linear coefficient since

But on the other hand, the functions below, they all describe parallel lines, since their slope has the same value. I've changed the letters to make it easier the comprehension.

Even though each one has the same slope value, they have different non zero linear coefficients, {-6,-18,6,18}. Unlike, the first one

`h(x)=3(9x-2) \rightarrow h(x)= 27x-6\\i(x)=9(3x-2)\rightarrow i(x)=27x-18\\j(x)=3(9x+2)\rightarrow j(x)=27x+6 \\k(x)=9(3x+2)\rightarrow k(x)=27x+18\\`

A possible solution would be adjusting any of these, whose operation would result in g(x)=3x, but

Like

`y=9((3x)/(9)-2)+18 =3x`
