$r=2\cos\theta$
$r^2=2r\cos\theta$
$\implies x^2+y^2=2x$
$x^2-2x+y^2=0$
$x^2-2x+1+y^2=1$
$(x-1)^2+y^2=1$

1. Reflect over x axis, right 1, up 8

2. Ref. over x, stretch 4 (up and down), up 6

3. Stretch 2 (side to side), left 9, down 5

4. stretch 8 ( s to s), reflect over y, down 4

5. Ref. over x, stretch 2/7 (s to s), up 5

Answer:

x = -1 or x = -7

Step-by-step explanation:

y = (x + 4)^2 - 9

To find x-intercept, set y = 0

=> (x + 4)^2 - 9 = 0

=> ( x + 1)( x + 7) = 0

=> x = -1 or x = -7
