Question

1.)G(x)=√(4-x)
a.G(4-x)
b.G(4-x^2 )
c.G(4-x^4 )
d.G(4x-x^2 )
e.G(-x^4-4x^2)

Answer 1

What's the question? .... Which of those options is G(x) = sqrt(4-x) equivalent to/

Answer 2

Evaluate the function at the indicated values

Answer 3

oh! derp. That makes sense. Are you having trouble with one in particular?

Answer 4

with all.. :/

Answer 5

:) none worries. Evaluating a function at a location just means substituting that location wherever x is in the original equation. So for the first one you take your original equation
\[ G_{(x)}= \sqrt{4-(x)}\]

and then replace that x with the expression (4-x),
\[ G_{(4-x)}= \sqrt{4-(4-x)}\]

Then simplify. You try #2 :)

Answer 6

wait.. how to simplify?

Answer 7

\[ G_{(4-x)}= \sqrt{4-4+x)}\]
\[ G_{(4-x)}= \sqrt{x}\]

Answer 8

let me try number 2. :)
