Question

Find the inverse function of
f(t)=75.457-0.707t

Answer 1

what do u think it will be

Answer 2

?

Answer 3

helo?

Answer 4

do you know how to do this? when you get the answer, it's f^(-1)(t) = (75.457-t)/0.707. This graph is a reflection of the original function over the line y = x.

Answer 5

To find the inverse function switch y with t and t with y and solve for y

so
y = 75.457-0.707t
becomes
t = 75.457-0.707y
=
0.707y = 75.457 - t
=
y = (75.457 - t)/0.707

thus

f^(-1)(t) = (75.457 - t)/0.707
