Let f(x)=x2−4x+3f(x)=\dfrac{x^{2}-4}{x+3}. Which one of the following statements about the value of lim⁡x→1f(x)\displaystyle \lim_{x\to 1} f(x) and f(1)f(1) is correct? a) lim⁡x→1f(x)\displaystyle \lim_{x\to 1} f(x) exists but is not equal to f(1)f(1). b) Neither lim⁡x→1f(x)\displaystyle \lim_{x\to 1} f(x) nor f(1)f(1) exists. c) Both lim⁡x→1f(x)\displaystyle \lim_{x\to 1} f(x) and f(1)f(1) exist and are equal. d) lim⁡x→1f(x)\displaystyle \lim_{x\to 1} f(x) does not exist but f(1)f(1) exists.
