...It would be helpful if you could explain how you solved it also.
For the first one, i need to know the y-intercept of this equation.
g(x)= (x^2 + x -12) / (x-3)
g(0) is the y-intercept
For this next one, i need to find the removable discontinuity, y-int, domain, and the function after the common factors have been eliminated.
f(t)= (t^4 - 16) / (t^2 +4t +4)
f(0) is the y-intercept
f(t) = [(t^2+4)(t+2)(t-2)]/[(t+2)(t+2)]
vertical asymptote at t = -2 ... so, what's the domain?
no removable discontinuities, because one factor of (t+2) remains in the denominator.
