Question

find the domain, points of discontinuity, and x- and y- intercept of each rational function? Determine whether the discontinuities are removable or non?

y = x^2+2x/x^2+2 (Its a fraction)

Answer 1

hint: x - intercept -> change y to zero then solve for x
y- intercept -> change x to zero then solve for y
domain -> equate x^2 + 2 = 0 solve for x..that is the value that is NOT part of the domain

Answer 2

so id the domain 0 and -2
