Answer:

${ \tt{f(x) = \sqrt[3]{x + 11} }}$

let the inverse of f(x) be m:

${ \tt{m = \sqrt[3]{x + 11} }} \\ { \tt{ {m}^{3} = x + 11}} \\ { \tt{ {m}^{3} - 11 = x}} \\ { \tt{ {f}^{ - 1}(x) = {m}^{3} - 11 }}$

substitute for x in place of m:

${ \bf{f {}^{ - 1}(x) = {x}^{3} - 11 }}$

3a-2b=14. 3a+2b=28<br>..

GaryK [48]

Answer:

a = 7

b = 3 1/2

Step-by-step explanation:

if you add the equations together then the 'b' will zero out

6a = 42

a = 7

substitute 7 for 'a' to solve for 'b'

3(7) - 2b = 14

21 - 2b = 14

-2b = -7

b = 7/2 or 3 1/2
