This problem is quite simple, but it may seem tricky at first.
y is a function of x, so replace y with f(x)
You get f(x) = 2x - 4
D is your answer.

What is the smallest solution to the equation 3x<img src="https://tex.z-dn.net/?f=%20x%5E%7B2%7D%20" id="TexFormula1" title=" x^

topjm [15]

IF you mean $3 x^{2} -16=131$ , then the following would be a solution:

First add 16 to both sides of the equation:
$3 x^{2} = 147$

Now divide both sides of the equation by 3:
$x^{2} =49$

Take the square root of both sides to solve for "X", or simply solve by inspection: "what number(s) can be squared to get 49?"

Answer: -7 and 7 So the smallest solution would be "-7"

To solve for x, add 3 to both sides, multiply both sides by -1, then take the square both sides.
$3- \sqrt{x} =0\\- \sqrt{x} =-3 \\ \sqrt{x} =3 \\ x=3^2=9$
