4. Verify that the functions fand g are inverses of each other by showing that f(g(x)) = x and g(f(x)) = x.

F(x)=2x-3/x+4
g(x) = 3+4x/2-x

Answer and step-by-step explanation:

We just have to apply one function in the other one. See:

→ f(g(x)):

→ g(f(x)):

What verifies that f and g are inverses of each other.

Q.E.D.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
