Question

help please??!!
What is the discontinuity and zero of the function f(x) = the quantity of 3 x squared plus x minus 4, all over x minus 1?

Discontinuity at (-1, 1), zero at (four thirds, 0)

Discontinuity at (-1, 1), zero at (negative four thirds , 0)

Discontinuity at (1, 7), zero at (four thirds , 0)

Discontinuity at (1, 7), zero at (negtive four thirds, 0)

Answer 1

\[f(x) = \frac{ 3x^2 +x-4 }{ x-1 }\]
