HELP ME HELP ME HELP ME!!! Given f(x) below, find f^-1(x).
elixir [45]

Answer:

f^{-1} (x) = 6 - 4x

Step-by-step explanation:

let y = f(x) and rearrange making x the subject

y = - \frac{1}{4} x + \frac{3}{2} ( multiply through by 4 to clear the fractions )

4y = - x + 6 ( subtract 6 from both sides )

4y - 6 = - x ( multiply through by - 1 )

- 4y + 6 = x

Change y back into terms of x with x = f^{-1} (x) , then

f^{-1} (x) = 6 - 4x

Find the area between the curves x=-2,x=3,y=4x,y=x-5
mixas84 [53]
Those are all lines...

So the x interval is from -2 to 3, because of x=-2 and x=3

The upper line is y(u)=4x and the lower line is y(l)=x-5

So the area between the two lines is:

A=⌠y(u)-y(l) dx

A=⌠4x-x+5 dx

A=⌠3x+5 dx

A=[3x^2/2+5x]

A=[(3x^2+10x)/2], x=[-2,3]

A=(1/2)(27+30-(12-20))

A=(1/2)(57+8)

A=(1/2)(65)

A=32.5 u^2
