If f(x) = (x^2-36)/(x+6) is continuous at x = -6, find f(-6) a)-12 b)12 c)6 d)-6

A

Step-by-step explanation:

Therefore, the correct answer is choice A. Hope this helps!

=-12

Step-by-step explanation:

f(x) = (x^2-36)/(x+6)

Factor the numerator.  The numerator is the difference of squares  

(a^2 -b^2) = (a-b)(a+b)

f(x) = (x-6)(x+6)/(x+6)

Cancel the like terms

f(x) = x-6

f(-6) = -6-6

       = -12

were is the equation

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
