Find the inverse of the logarithmic function y =log₂(x + 7) y = x2 - 7 y = x2 + 7 y = 2x2 + 7 y = 2x - 7 y = 2x + 7

1. Interchange x and y: x = log₂(y + 7)

2. Solve this resulting equatino for y:

x x

2 = y + 7 => y = 2 - 7

3. Replace "y" with

-1 -1 x

f (x): f (x) = 2 - 7 This is the desired inverse.

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
