Question

what is the discontinuity and zero of the function f(x)=2x^2+5x-12/x+4?

Answer 1

it is not continuous at \(x=-4\) because the denominator would be zero there

Answer 2

factor and cancel to finish the problem

Answer 3

2x3 + 5x2 + 4x - 12/x

Answer 4

Answer 5

x = 0 (infinite discontinuity) (left limit: infinity | right limit: -infinity)
(assuming a function from reals to reals)
