What is the inverse of the function f(x) = 2x+ 1?A. h(x) = 1/2x -1/2
B. h(x) = 1/2x + 1/2
C. h(x) = 1/2x - 2
D. h(x) = 1/2x + 2

Answers

$f(x) = 2x + 1$

$y = 2x + 1$

Subtract sides -1

$y - 1 = 2x + 1 - 1$

$y - 1 = 2x$

$2x = y - 1$

Divided sides 2

$(2)/(2)x = (y - 1)/(2) \n$

$x = (1)/(2)y - (1)/(2) \n$

Thus ;

${f}^( - 1) = h(x) = (1)/(2)x - (1)/(2) \n$
