How are the graphs of the functions f(x) = . 16and g(x) = 3/64 related?

Natalija [7]

Answer: A there are equivalent.

Step-by-step explanation:

f(x) = $\sqrt{16}^x$ reduces to f(x)= $4^{x}$

g(x)= $\sqrt[3]{64}^{x}$ also reduces to g(x) = $4^{x}$

How to sovle <br> (x+1/x)^2

Slav-nsk [51]

$(\frac{x + 1}{x} ) ^{2} \\ = \frac{ {(x + 1)}^{2} }{ {x}^{2} } \\ = \frac{ (x + 1)(x + 1) }{ {x}^{2} } \\ = \frac{ {x}^{2} + 2x + 1}{ {x}^{2} }$

Hope you could get an idea from here.

I need help with number 4

Tju [1.3M]

So you first want to move all variables to one side.

2x = 1/8 + 4x

So perform the opposite of each operation to move it.

2x - 4x = 1/8 + 4x - 4x

-2x = 1/8

And then just divide both sides by -2

-2x / -2 = 1/8 / -2

x = -1/16
