# Let f(x) = x2 81. Find f-1(x) [Solved] In fact the function does not have an inverse. It is
not one-to-one, since, say, if f(x)=19, x^2=100 and x=-10
or x=10. To have an inverse there should only be one
value of x.

Let,
y = x 81
x=y 81
x=(y 81)

In fact the function does not have an inverse. It is
not one-to-one, since, say, if f(x)=19, x^2=100 and x=-10
or x=10. To have an inverse there should only be one
value of x.

f(x) = x2 81
y = x^2 81
x = y^2 81
x 81 = y^2
y = (x 81)

In fact the function does not have an inverse. It is
not one-to-one, since, say, if f(x)=19, x^2=100 and x=-10
or x=10. To have an inverse there should only be one

y = f(x) = x^2 6x dy/dx= 2x 6 x = 2 and dx = 25 dy= [2(2) 6] * 25 =250 preliminary x= 2 (replace) x= 25 (replace)y/ (replace)x = dy/dx x= 2 (replace)y= [2(2) 6] * 25 = 250

f(x) = (x 81) answer//

y 81 = x^2
x = ( or -) sqrt[y 81]

A

y = f(x) = x^2 6x dy/dx= 2x 6 x = 2 and dx = 25 dy= [2(2) 6] * 25 =250 preliminary x= 2 (replace) x= 25 (replace)y/ (replace)x = dy/dx x= 2 (replace)y= [2(2) 6] * 25 = 250
