Question

Find a formula for the described function. Express the area of an equilateral triangle as a function of the length of a side x. A(x) = 3 4x2 state the domain of

a. (enter your answer using interval notation.)

Answer 1

Answer:

See below.

Step-by-step explanation:

The area of an equilateral triangle is given by,

$A = \frac{\sqrt{3}}{4} a^2$

Where a is the length of the side of the traingle. Expressing this as a function of x where x is the length of the side,

$f( x ) = \frac{\sqrt{3}}{4}x^2$

Which yields the area of the equilateral triangle given the length of its side.

Answer 2

Answer:

Step-by-step explanation:

As we know that area of equilateral triangle is √ 3/4 a^2

But here side is X

So in notation it will be....

f(x) =√3/4X^2...
