Answer:
A
Step-by-step explanation:
Call f(x) = y
y = 2x + 1 Interchange x and y
x = 2y + 1 Subtract 1 from both sides
x - 1 = 2y + 1 - 1
x - 1 = 2y Divide by 2
x/2 - 1/2 = 2y/2 Do the division
1/2 x - 1/2 = y
h(x) = 1/2x - 1/2
C and D cannot be correct. The y intercept is -1/2 not 2.
So it is between A and B.
The y intercept is - 1/2
The correct answer is A
