If f(x) = 3x2, find the inverse of f.

Nostrana [21]

Answer:

The inverse of f is

$y = \sqrt{ \frac{x}{3} }$

Step-by-step explanation:

f(x) = 3x²

To find the inverse of f equate f(x) to y

That's f(x) = y

We have

y = 3x²

Interchange the terms

x = 3y²

<u>Make y the subject</u>

x = 3y²

<u>Divide both sides by 3</u>

${y}^{2} = \frac{x}{3}$

Find the square root of both sides to make y stand alone

That's

$\sqrt{ {y}^{2} } = \sqrt{ \frac{x}{3} }$

The final answer is

$y = \sqrt{ \frac{x}{3} }$

Hope this helps you

Verify identity list steps. Cot(t)(1-cos^2(t))=cos(t)sin(t)

storchak [24]

Remember: We have to work from either the LHS or the RHS.
(Left hand side or the Right hand side)

You should already know this:

$\huge{Cot(t) = \frac{1}{tan(t)} = \frac{1}{\frac{sin(t)}{cos(t)}} = 1\div \frac{sin(t)}{cos(t)} = 1\times \frac{cos(t)}{sin(t)}=\boxed{\frac{cos(t)}{sin(t)}}$

You should also know this:

$sin^2(t) + cos^2(t) = 1\\\\\boxed{sin^2(t)} = 1 - cos^2(t)$

So plugging in both of those into our identity, we get:

$\frac{cos(t)}{sin(t)}\cdot sin^2(t) = cos(t)\cdot sin(t)$

Simplify the denominator on the LHS (Left Hand Side)

We get:

$cos(t) \cdot sin(t) = cos(t) \cdot sin(t)$

LHS = RHS

Therefore, identity is verified.
