Solve 2√x=1-√(4x-1).

andriy [413]

Answer: $x=\frac{1}{4}$

Step-by-step explanation:

Given

$2\sqrt{x}=1-\sqrt{4x-1}$

$\sqrt{4x-1}=1-2\sqrt{x}$

Squaring both sides

$4x-1=1+4x-4\sqrt{x}$

$4\sqrt{x}=2$

$\sqrt{x}=\frac{1}{2}$

squaring both sides

$x=\frac{1}{4}$

Which is the graph of the cube root function f(x) = RootIndex 3 StartRoot x EndRoot?

lara [203]

Answer:

<h3>On a coordinate plane, a cube root function goes through (negative 8, negative 2), has an inflection point at (0, 0), and goes thorugh (8, 2).</h3>

Step-by-step explanation:

$f(x)=\sqrt[3]{x}\\\\f(-8)=\sqrt[3]{-8}=-2\to(-8,\ -2)\\\\f(0)=\sqrt[3]{0}=0\to(0,\ 0)\\\\f(8)=\sqrt[3]{8}=2\to(8,\ 2)\\\\\\\sqrt[3]{a}=b\iff b^3=a\\\\\text{Therefore:}\\\\\sqrt[3]{-8}=-2\ \text{because}\ (-2)^3=-8\\\sqrt[3]0=0\ \text{because}\ 0^3=0\\\sqrt[3]{8}=2\ \text{because}\ 2^3=8$
