What are the discontinuity and zero of the function f(x) = quantity x squared plus 5 x plus 6 end quantity over quantity x plus 2?A. Discontinuity at (−2, 1), zero at (3, 0) B. Discontinuity at (−2, 1), zero at (−3, 0) C. Discontinuity at (2, 5), zero at (3, 0)D. Discontinuity at (2, 5), zero at (−3, 0)

Answer:B. Discontinuity at (−2, 1), zero at (−3, 0)Step-by-step explanation:The given function is:[tex]\frac{x^{2}+5x+6}{x+2}[/tex]The expression in numerator can be expressed as factors as shown below:[tex]\frac{x^{2}+5x+6}{x+2}\\\\ =\frac{x^{2}+2x+3x+6}{x+2}\\\\ =\frac{x(x+2)+3(x+2)}{x+2}\\\\ =\frac{(x+2)(x+3)}{x+2}[/tex]Note that for x = -2, both numerator and denominator will be zero. When both the numerator and denominator of a rational function are zero for a given value of x we get a discontinuity at that point. This discontinuity is known as a hole. This means there is a hole at x = -2Cancelling the common factor from numerator and denominator we get the expression f(x) = x + 3Using the value of x = -2 in previous expression we get:f(x) = -2 + 3 = 1Thus, there is a discontinuity(hole) at (-2, 1)For x = -3, the value of the expression is equal to zero. This means x = -3 is a zero or root of the function.Thus, (-3, 0) is a zero of the function.Therefore, option B would be the correct answer.
