#1**+1 **

We'll save (a) for last

(b) 3 / x = 4x + 4 this will have two real solutions

(c) Multiply both sides by x

3 = 4x^2 + 4x rearrange as

4x^2 + 4x - 3 = 0 factor

(2x - 1) (2x + 3) = 0

Set both factors to 0 and solve for x and we get x = 1/2 or x = -3/2

When x = 1/2 ...... y = 3 / (1/2) = 6

When x = -3/2.......y = 3 / (-3/2) = -2

So..intersection pts are (1/2, 6) and ( -3/2, -2)
