1 f(x) = 2x

Step by step solution Step 1 of 5 Simplify the expressions f(x)f(and f(x+h)f(if f(x) =1 . xa h 2x Step 2 of 5 First let’s find the value of function f(a) by putting the = a in the relation for the f nction (x): f(x) = 1 1x f(a) = 2a…. (1) Step 3 of 5 Based on the relation (1) we can find the value of expression f(x)f:a) xa f(x)f(a) 2x 2a = xa xaa x 2xa 2xa = xa ax 2xa = xa xa 2xa = xa = 1 2ax
