Identify the inverse g(x) of the given relation f(x).
Leno4ka [110]

Answer:

g(x) = {(3, 8), (1, 4), (-1,0), (-3, 4);

Step-by-step explanation:

Recall and use the fact that, the domain of a relation becomes the range of its inverse and vice-versa.

Base on the possible answers ,the given relation is f(x) = {(8,3), (4, 1), (0, -1), (4,-3)}

To find an inverse relation for f(x), we need to swap the x and y coordinates of f(x).

The inverse of f(x) will have the ordered pairs: (3,8),(1,4),(-1,0),(-3,-4)

Therefore the correct choice is g(x) = {(3, 8), (1, 4), (-1,0), (-3, 4);

2x²-12x+8 = 0 <br><br>solve for x ​
Luda [366]

Answer:

x = 3 + sqrt(5) or x = 3 - sqrt(5)

Step-by-step explanation:

Solve for x over the real numbers:

2 x^2 - 12 x + 8 = 0

Divide both sides by 2:

x^2 - 6 x + 4 = 0

Subtract 4 from both sides:

x^2 - 6 x = -4

Add 9 to both sides:

x^2 - 6 x + 9 = 5

Write the left hand side as a square:

(x - 3)^2 = 5

Take the square root of both sides:

x - 3 = sqrt(5) or x - 3 = -sqrt(5)

Add 3 to both sides:

x = 3 + sqrt(5) or x - 3 = -sqrt(5)

Add 3 to both sides:

Answer: x = 3 + sqrt(5) or x = 3 - sqrt(5)
