Question

If f(x)= 2^(x-5)find f(8)

Answer 1

`\\ \rm\hookrightarrow f(x)=2^(x-5)`

f(8):-

`\\ \rm\hookrightarrow 2^(8-5)`

`\\ \rm\hookrightarrow 2^3`

`\\ \rm\hookrightarrow 8`

Answer 2

`\huge\boxed{\sf f(8) = 8}`

Explanation:

Given function:

`f(x) = 2 ^((x-5))`

Put x = 8

`f(8) = 2^((8-5))\\\\f(8) = 2 ^3\\\\f(8) = 2 * 2 * 2\\\\f(8) = 8\\\\\rule[225]{225}{2}`
