What is the solution set of the equation 6x^2 - 18x - 18 =6?
dybincka [34]

Answer:

The solution set is {4, -1}

Step-by-step explanation:

6x²- 18x -18 = 6

6x²- 18x -18 - 6 = 0

6x²- 18x -24 = 0

6(x² - 3x - 4) = 0

6(x - 4)(x + 1) = 0

6 = 0 not true

x - 4 = 0 ;   x + 1 = 0

x = 4           x = - 1

The solution set is {4, -1}

Talib is trying to find the inverse of the function to the right. His work appears beneath it. Is his work correct? Explain your
lianna [129]
Given the function
f(x)=-8x+4

The inverse of the function is calculated by changing f(x) to y and making x the subject of the formula as follows:
y=-8x+4 \\  \\ y-4=-8x \\  \\ x= \frac{y-4}{-8}

We now change back the variables to get the function in the form of inverse function as follows:
f^{-1}(x)=\frac{x-4}{-8}

Comparing this with Talib's work, we can see that he is correct except for the last line where he did not change the variable y back to x.

Therefore, the last line of his work made his inverse not to be correct.
