Which is the inverse of the function f(x) = 4x2
Sholpan [36]

Answer:

\sqrt{\frac{x}{4}}  and  -\sqrt{\frac{x}{4}}

Step-by-step explanation:

The function is given as  f(x)=4x^2

<em>to find inverse, we follow the steps shown below:</em>

<em>1. write "y" in place of "f(x)"</em>

<em>2. interchange "x" and "y"</em>

<em>3. solve for the new "y"</em>

<em>4. replace y with f^-1(x)</em>

<em />

Let's do this:

f(x)=4x^2\\y=4x^2\\x=4y^2\\y^2=\frac{x}{4}\\y=+-\sqrt{\frac{x}{4}}

These 2 are the inverse functions.

pablo will rent a car for the weekend. he can choose one of two plans. the first plan has an initial fee of $55.96 with addition
kow [346]

Answer:

200 miles

Step-by-step explanation:

First, set up the equations.

plan 1: initial fee of $55.96, $0.12 per mile

  • y = 0.12x + 55.96

plan 2: initial fee of $63.96, $0.08 per mile

  • y = 0.08x + 63.96

We want to know at what distance will the cost be the same. So, set the equations equal to each other.

0.12x + 55.96 = 0.08x + 63.96

Combine the variables.

0.04x + 55.96 = 63.96

Combine the constants.

0.04x = 8

Divide by 0.04 to isolate x.

x = 200 miles

Check by plugging x back into each equation.

y = 0.12(200) + 55.96

y = 24 + 55.96

y = $79.96

y = 0.08(200) + 63.96

y = 16 + 63.96

y = $79.96

You are correct!
