The equation of the directrix is x = -3

<h3>What is Parabola?</h3>

A mirror-symmetrical, roughly U-shaped plane curve known as a parabola. It corresponds to a number of mathematical models that appear to be superficially dissimilar but yet all define the exact same curves. A point and a line are one way to describe a parabola.

<h3>According to the given information: </h3>

Given the general equation of a parabola expressed as

(y-y0)² = 4a(x-x0) ... 1

Equation of the directrix will be expressed as x = x0 - a

From the equation given;

y² = 12x ... 2

Comparing 1 and 2;

x - x0 = x

-x0 = x - x

-x0 = 0

x0 = 0

Similarly;

y-y0 = y

-y0 = y - y

-y0 = 0

y0 = 0

Also;

4a = 12

a = 12/4

a = 3

Substituting x0 =0, y0 = 0 and a = 3 into the equation of the directrix above, we will have;

x = x0 - a

x = 0 - 3

x = -3

Hence,

the equation of the directrix is x = -3

What value does stage theories of development have
siniylev [52]
If human development really does proceed continuously, what value does stage theories of development have?

Answer:

Even if human development is continuous, there is some value in stage theories of development. A stage theory of development allows experts to examine the developmental progress of individuals and establish a basis for developmental changes. This can help identify developmental issues earlier. Stage theories can also help researchers who are examining physical development examine discrete changes in the brain that allow certain developmental milestones to be reached. Finally, stage theories can give one a sense of where an individual is developmentally, and can prepare the person for changes that may occur during their lifetime.
