Where is the removable discontinuity of f (x) = x+5/x^2+3x-10 located

a. x=-5

b. x=-2

c. x=2

d. x=5

We are tasked to solve for the removable discontinuity of the expression below:

f (x) = (x+5) / (x²+3x-10)

Factoring the denominator, we have:

f (x) = y = (x+5) / (x+5) (x-2)

Canceled out (x+5) which is common in numerator and denominator, we have:

y = 1 / (x-2)

Removable discontinuity is (x+5) or x = - 5. The answer is the letter "A".
