Question

What should be the value of y when x = -1 to remove all discontinuities of f(x) = x^3 - 3x^2 - x + 3/x + 1

Answer 1

is x+1 denominator in the expression

Answer 2

yes

Answer 3

wait a minute

Answer 4

if x+1 is denominator for the whole expression, y will be 6 to remove the discontinuity

Answer 5

sorry 8

Answer 6

okay

Answer 7

y=8 removes the discontinuity

Answer 8

if you need the steps

Answer 9

no i got it i got 8 but wanted to make sure

Answer 10

first divide the numerator by the denominator

Answer 11

then evaluate the quotient at x=-1

Answer 12

ok
