3x -1 = 11
3x = 11 + 1
3x = 12
x = 4
I take it by, x2 + x, you mean 2x + x, since x = 4, then
2x + x = 2(4) + (4) = 8 + 4 =12
Answer:
y = 19/14 and x = 25/42
Step-by-step explanation:
Answer:
Option B.
Step-by-step explanation:
Inverse function:
Suppose we have a function y = f(x). To find the inverse function, we exchange x and y on the original function, and then isolate y.
The domain of the inverse function(x values) is the range of the original function(y values).
Original function:
Domain is , and when . So the range is , that is,
Inverse function:
Exchanging x and y
The inverse function is
Domain:
Range of the original function is , so the domain of the inverse function is . The correct answer is given by option B.
