Please see attached image for full understanding of the solution
If we plot the function we can see that it has a discontinuity at x = 1.
Also,
If we evaluate at x = -9, we see that the values of the piecewise function in both cases are completely different.
Therefore, x = -9 is also a discontinuity.
The right answer is option a
(discontinuity at x = 1 and x = -9)
When you solve a proportion, your first step should be to cross-multiply.
= 
When you cross-multiply, you should get this equation:
(2x)(3) = (x + 3)(5)
Now, solve it using algebra.
(2x)(3) = (x + 3)(5) Multiply
6x = 5x + 15 Subtract 5x from both sides
x = 15
The value of x is 15.
