Question

Y=4X^2 make x the subject of formula

Answer 1

Answer:

$x=\pm{\frac{\sqrt{y}}{2} }$

Step-by-step explanation:

Given the equation

$y=4x^{2}$

If we remember this represents a parabola symmetric about the y axis.

The above equation can be written as

$x^2=\frac{y}{4}$

$\implies x=\pm\sqrt{\frac{y}{4} }$

$\implies x=\pm{\frac{\sqrt{y}}{2} }$

Thus making x the subject of the formula we get

$x=\pm{\frac{\sqrt{y}}{2} }$
