Question

I need to know the answer

Answer 1

A

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
