If y+32y+5=sin⁡2x+2cos⁡x+1\frac{y+3}{2y+5} = \sin^2 x + 2 \cos x + 1 , then the value of yy lie in the interval a. (−∞,−83]\left(-\infty, -\frac{8}{3}\right] b. [−125,∞)\left[-\frac{12}{5}, \infty\right) c. [−83,−125]\left[-\frac{8}{3}, -\frac{12}{5}\right] d. (−∞,−83]∪[−125,∞)\left(-\infty, -\frac{8}{3}\right] \cup \left[-\frac{12}{5}, \infty\right)
