To find the value of g^(-1) o g(2), we need to determine the input value that would produce an output of 2 when fed into the function g(x).
Let's begin by finding the inverse function of g(x). We can start by replacing g(x) with y in the equation and then solving for x.
Given:
g(3x - 2) = 7x - 15
Replacing g(x) with y:
y = 7x - 15
Now, let's solve for x in terms of y:
y = 7x - 15
y + 15 = 7x
x = (y + 15) / 7
Therefore, the inverse function g^(-1)(x) is:
g^(-1)(x) = (x + 15) / 7
Now we can find g^(-1) o g(2) by plugging g(2) into g^(-1)(x):
g^(-1) o g(2) = g^(-1)(g(2))
= g^(-1)(7(2) - 15)
= g^(-1)(14 - 15)
= g^(-1)(-1)
Plugging -1 into g^(-1)(x):
g^(-1)(-1) = (-1 + 15) / 7
= 14 / 7
= 2
Therefore, the value of g^(-1) o g(2) is indeed 2.
